Summary
- No regulations protect comfort — Comfort is not a legal right for non-disability reasons; airlines can make seats as tight as they want.
- Aircraft choice matters more than airline — Seat width varies dramatically by aircraft type and configuration.
- Premium Economy can cost less than two economy seats — On long-haul routes, Premium Economy often provides better value.
- Some airlines offer discounted adjacent seats — They sell neighboring seats at reduced rates, or offer “neighbour-free” products.

The tall & plus-size guide to Asia flights (2025 edition)
Your body isn’t “oversized”—the seat is under-designed.
If you’re tall or plus-size and facing a 12-hour Asia flight, your comfort comes down to three things: choosing the right aircraft, understanding airline policies, and knowing which seats to book (or avoid).
This guide gives you the aircraft specs, regulatory facts, and booking tactics to fly Asia routes without gambling on legroom or width.
Your rights vs. reality — the policies that actually matter
The uncomfortable truth about seat size rules
The FAA examined seat dimensions for safety purposes, not comfort, and as of 2025 there is no mandated minimum seat size. An appeals court ruled the FAA is not required to set seat size minimums, citing insufficient safety evidence.
Translation: No US regulation protects you from narrow or tight seats. Comfort is not a legal requirement.
Disability accommodations (not size accommodations)
US regulations clarify disability seating accommodations but do not create a general right to free extra seats for non-disability size concerns. Carriers must provide appropriate seating within the class of service purchased for passengers with disabilities, but this obligation applies specifically to disability contexts.
Canada’s One-Person-One-Fare (OPOF) applies for disability-related extra-seat needs on domestic travel with eligible carriers. It’s not a blanket accommodation for size alone, and it requires documentation.
EU Regulation 1107/2006 establishes rights for disabled persons and those with reduced mobility, including seating accommodation obligations, but again, this is not a general size or weight policy.
Exit-row restrictions
Federal regulations define exit-seat suitability and operator obligations. Delta’s policy states that passengers who require the use of a seat belt extension are not permitted in exit rows. This aligns with FAA safety intent: exit-row occupants must be able to assist in an evacuation without impediment.
If you anticipate needing a seat-belt extender, do not pay for an exit row. You’ll be moved, and many airlines won’t refund the upgrade fee.
Seat-belt extenders
Passenger-owned seat-belt extenders are not approved by the FAA; passengers must use airline-provided extenders. Bringing your own is not just discouraged—it’s prohibited for safety reasons.
Most airlines carry extenders of approximately 63 cm; politely request one from cabin crew during boarding.
Southwest’s switch (and what to do instead)
Southwest is ending the policy that made it the go-to carrier for passengers of size.
For years, Southwest’s “Customer of Size
” policy let passengers request a second seat at the gate or onboard, with refunds available when flights weren’t oversold. You could show up, assess your comfort needs in real-time, and handle it without advance planning.
That safety net disappears in . The airline will now require pre-purchase of second seats, implement assigned seating, and tighten refund conditions—eliminating the flexibility that set it apart.
Your alternatives
Alaska Airlines offers the most Southwest-like approach among major carriers. If you can’t be seated with armrests down, you’re required to purchase an additional seat—but Alaska has historically refunded the extra seat when flights depart with empties. Verify current terms when booking, as policies evolve.
United and American both enforce the armrest-down standard and require second seat purchases, but their refund policies lack Alaska’s flexibility. You’re more likely to pay for both seats regardless of load.

Quick wins — what to book right now
Sometimes the answer isn’t a friendlier policy. It’s a wider aircraft.
Aircraft you want
A350 and A330 configured 2-4-2 typically offer wider seats than 9-abreast 787s or 10-abreast 777s. Airbus markets approximately 18-inch economy seats on many configurations, while tighter 787 and 777 layouts squeeze closer to 17–17.5 inches.
The exception: JAL’s 787 “Sky Wider” uses a 2-4-2 configuration with approximately 48 cm (about 19 inches) width and 84–86 cm pitch. This is a genuine outlier in widebody economy. Japan Airlines’ 777-300ER economy also delivers 34″ pitch × 19″ width—very generous for economy class.
Standout configurations by carrier:
- Singapore Airlines A330-300: 32″ × 19″ (exceptionally roomy width).
- Singapore Airlines A350/A380: 32″ × 18-19″ (consistent comfort).
- Delta A330-300: 35″ × 18″ (excellent legroom).
- Delta 767-400ER: 38″ × 19″ (best-in-class for economy).
- EVA Air 777-300ER: 33″ × 18.3″ (solid all-around).
- Korean Air 777/A380: 33-34″ × 18″ (wide seats, good pitch).
Configurations to avoid:
- Standard 787s in 3-3-3: Often 17.2-17.5″ width (United 787-9: 35″ × 17.3″; ANA 787-8: 31″ × 17.2″).
- 10-abreast 777s: Around 17-17.1″ width (American 777-200: 36″ × 17″; Emirates 777: 33″ × 17″).
- Emirates A380 3-class: 32-34″ pitch but only 17.5″ width.
Routes worth targeting
- SYD–NRT on JAL 787 (2-4-2) or 777-300ER: Wider seats (19″), better pitch (34″).
- LAX–SIN on Singapore Airlines A350: Consistent 18-19″ economy.
- LHR–HKG on Cathay A350 or 777/A330: 32″ × 18″ seats.
- LAX–Tokyo on Delta A330 or 767: Up to 38″ × 19″ on some 767-400ER configurations.
- Amsterdam–Singapore on KLM 787-9: 35″ × 17.5″ with excellent pitch.
| Origin Region | Destination | Best Carrier/Aircraft | Seat Dimensions | Typical Economy Fare |
|---|---|---|---|---|
| US West Coast | Tokyo | JAL 777-300ER / 787 Sky Wider | 34″ × 19″ / 33-34″ × 19″ | $600-800 |
| US West Coast | Singapore | Singapore Airlines A350 | 32″ × 18-19″ | $800-1,000 |
| US East Coast | Hong Kong | Cathay Pacific A350 | 32″ × 18″ | $700-900 |
| US (select) | Asia via Delta | Delta 767-400ER | 38″ × 19″ | $700-1,000 |
| London | Singapore | Singapore Airlines A350/A380 | 32″ × 18-19″ | £560-600 (~$700-750) |
| London | Hong Kong | Cathay Pacific A350 | 32″ × 18″ | £500-700 |
| Amsterdam | Singapore | KLM 787-9 | 35″ × 17.5″ | €600-800 |
| Sydney | Singapore | Singapore Airlines A380 | 32″ × 19″ | AUD 724 (~$470) |
| Sydney | Tokyo | JAL 787 Sky Wider / 777-300ER | 33-34″ × 19″ | AUD 800-1,000 |
Simple comfort tactics
- Choose an aisle seat. An aisle lets you stretch legs into the aisle periodically and provides more lateral space for shoulders and hips. KLM explicitly recommends aisle seats for passengers needing extra shoulder or hip room.
- Board early. If your fare class allows early boarding, use it. Stow baggage efficiently and minimize carry-on bulk at your feet to maximize legroom. Keep only essentials under the seat in front.
- Consider buying two seats. Some airlines offer adjacent seat purchases at reduced rates. KLM allows purchasing an adjoining seat at approximately 75% of the normal fare, effectively doubling your personal space without jumping to Premium Economy pricing.
Tall traveler playbook
Standard economy on Asia long-hauls runs 30–32 inches. That’s punishing for 12+ hours if you’re tall. Pitch (the distance between seat backs) will determine your knee clearance.
Exceptional standard economy pitch:
- Delta 767-400ER: 38″ × 19″ (best legroom in US carrier economy).
- Delta 777-200LR: 33″ × 18.5″.
- American 777-200 (3-class): 36″ × 17″ on LAX–HKG and similar routes.
- American 777-300ER (newer): 36″ × 17.1-18.1″.
- United 777-300ER: 34″ × 17.05″ (varies by configuration).
Extra-legroom products worth buying:
- United Economy Plus offers up to approximately 6 inches of additional legroom (many 787s offer 35″ pitch in Economy Plus rows).
- Delta Comfort+ provides up to approximately 3 inches extra, with some international A330s reaching 35″ pitch.
- American’s Main Cabin Extra adds up to approximately 6 inches, with some 777-200s offering 36″ pitch.
For travelers 6’2″ and above, those 3–6 inches are the difference between tolerable and miserable. The “up to” qualifier matters: pitch varies by aircraft subfleet, so verify the exact row on your flight’s seat map.
Booking timeline
Strategic timing can save you hundreds of dollars and secure better seating, so follow this phased approach from initial research through check-in.
- 3-6 months out: Research aircraft types on your route; book refundable if unsure about equipment.
- At booking: Select seats immediately; verify configuration matches expectations.
- 2-3 months out: Purchase extra-legroom or Premium Economy if prices are favorable.
- 4 weeks out: Final check for aircraft swaps; re-select seats if needed.
- 72 hours out: Check for last-minute upgrades or unsold Premium Economy (sometimes released cheap).
- 24 hours out: Online check-in; request seat-belt extender if needed; verify neighbor-free purchase (Emirates).
Plus-size playbook
The armrest-down standard
Most US carriers use an “armrest-down” operational trigger. If you cannot remain seated with armrests down without encroaching on adjacent seats, an additional seat is required.
This isn’t arbitrary—it’s the airline’s way of defining when one passenger’s space impinges on another’s.
Aircraft selection is everything
Width by configuration:
- Singapore Airlines A330-300: 32″ × 19″ (exceptional—widest economy).
- JAL 777-300ER: 34″ × 19″ (widest among Asian carriers).
- Delta 767-400ER: 38″ × 19″ (best US carrier width + pitch).
- A350 and A330 in 2-4-2 layouts: approximately 18 inches per seat.
- JAL 787 “Sky Wider” exception: Approximately 19 inches width in 2-4-2 configuration with 33-34″ pitch.
That 1.5–2 inch difference is significant. If you’re broad-shouldered or have wider hips, targeting A350/A330 routes, JAL configurations, or Singapore Airlines can eliminate the need for a second seat entirely.
Routes to prioritize
Avoid 10-abreast 777s and standard 3-3-3 787s where possible. The width penalty compounds over 12–16 hours.
Budget alternatives
Low-cost carriers like Jetstar and AirAsia (SYD–BKK/DPS) offer fares under AUD 500 roundtrip but typically feature very tight seats (approximately 30″ pitch × 17″ width) with no frills. These are not recommended for plus-size or tall travelers on flights over 4-5 hours.
How to book an extra seat or neighbor-free
Buying a second seat on US carriers
Most US airlines require you to purchase the second seat in the same fare class at the same price. Here’s how:
- United: Call reservations or book online (some fare classes allow multi-seat bookings). Use a placeholder name like “EXTRA SEAT” for the second passenger.
- American: Similar process; must be same fare class.
- Alaska: Purchase an additional seat if unable to remain seated with armrests down. Alaska has historically offered refunds if the flight departs with empty seats—verify current policy.
- Southwest (): Current policy allows refund requests for extra seats. After , pre-purchase will be required with stricter refund conditions.
International carriers
- Emirates: Emirates allows purchase of up to 3 adjoining seats at check-in, subject to availability, but this is not advance-bookable. You must buy at the airport—usually 4–24 hours before departure. Price is typically the prevailing economy fare.
- Etihad: Etihad sells an “Economy Neighbour-Free” product that keeps up to 3 neighboring seats free, with route and availability limits. This can be booked in advance through their website or contact center. Pricing varies but typically ranges from $100–$300 per segment depending on route length.
- Air New Zealand: Air New Zealand offers a “Twin Seat” product to hold the seat next to you for additional space, though not available on all routes. Book via “Seat + Bag” during reservation or manage booking.
- Lufthansa: Some routes offer a “Neighbor Free Seat” pre-purchase option, but availability is limited and route-specific.
- KLM: Allows purchasing an adjacent seat at approximately 75% of the normal fare—significantly cheaper than buying two full-price tickets. This effectively doubles your personal space without Premium Economy pricing.

Exit-rows & bulkhead seats
Federal requirements for exit rows
Federal regulations impose strict requirements on who can sit in exit rows. Airlines must ensure these passengers can understand instructions in the local language, have adequate hearing and vision, possess the physical strength and mobility to open emergency exits, and are able to assist other passengers without impediment.
If you require a seat-belt extension, you are not permitted in exit rows—this rule is non-negotiable and applies across all airlines.
Exit rows aren’t always better
If you’re tall, exit rows are usually your best option for legroom. However, they come with several trade-offs that can make them less comfortable for plus-size travelers:
- Immovable armrests: Many exit-row seats have fixed armrests to house the tray table, which slightly reduces effective seat width.
- Colder cabin temperatures: Proximity to exit doors often means a noticeably colder flight.
- Tray table stored in armrest: Makes meals awkward to manage.
- No under-seat storage: Regulations require clear floor space, so you can’t stow a personal item at your feet during takeoff and landing.
- Protrusion from emergency equipment: Some exit rows have door mechanisms or slide housings that actually eat into legroom despite the nominal pitch advantage.
Bulkhead seats: the alternative
Bulkhead seats (the first row behind a dividing wall) offer legroom without exit-row restrictions and come with their own set of advantages:
- Legroom without exit-row restrictions.
- No seat recline from the row in front.
- Often first to deplane.
- Can offer excellent leg stretch (verify specific aircraft configuration).
However, bulkhead seats share some drawbacks with exit rows. You’ll have no under-seat storage during taxi, takeoff, and landing, which means everything must go in the overhead bin. If the bulkhead has bassinet mounts for families with infants, these can restrict where you position your feet. Like exit rows, bulkhead seats typically have tray tables stored in the armrests, making the seat slightly narrower.
Premium Economy versus two economy seats
When deciding between Premium Economy and purchasing two economy seats, the best choice depends on route length, airline pricing policies, and your specific needs.
Here’s how to evaluate both options.
The Premium Economy advantage
Premium Economy provides meaningful upgrades over standard economy: you’ll get 38-40 inches of legroom compared to 30-32 inches, seat widths of 18.5-19.5 inches versus 17-18 inches, and significantly more recline—typically 5-7 inches of movement compared to just 3-4 inches in economy.
Typical Premium Economy dimensions:
- Japan Airlines 777-300ER: 42″ × 19″ (exceptional).
- ANA 787-8/777-300ER: 38″ × ~19″.
- Singapore Airlines A350/787: 38″ × 19″.
- Qantas A330/787: 38″ × 19″.
- Korean Air: 38″ × 19″.
- British Airways 787-9 (World Traveller Plus): 38″ × 18″.
- EVA Air Premium: 38″ × 18.3″.
Beyond physical comfort, Premium Economy includes perks like enhanced meal service, priority boarding, and additional baggage allowance.
The pricing typically runs 90-100% more than a standard economy ticket, essentially doubling your fare.
However, Premium Economy becomes the clear winner when compared to buying two economy seats on long-haul flights.
Consider a 17-hour journey from Los Angeles to Singapore: if economy costs $800 per seat, purchasing two seats would total $1,600, while Premium Economy might cost only $1,400. In this scenario, you save $200 while gaining superior comfort, better service, and all the premium cabin benefits—making it the smarter financial and practical choice.
When two economy seats make more sense
Despite Premium Economy’s advantages, buying two economy seats can be the better option in specific situations:
- Short-haul Asian routes under 8 hours: The substantial premium cabin surcharge often doesn’t justify the comfort improvement for brief flights.
- Airlines with refund policies: Some carriers like Alaska Airlines have historically refunded the cost of a second seat if the flight departs with empty seats, letting you hedge your bet and potentially fly with extra space for the price of one ticket.
- Discounted adjacent seat programs: KLM offers adjacent seats at 75% of the standard fare, making two economy seats considerably cheaper than Premium Economy on many routes.
- Award ticket availability: You may find it easier to book two economy award seats than securing the often limited Premium Economy award inventory.
The decision ultimately comes down to flight duration and specific airline pricing. For long-haul flights where Premium Economy costs less than two economy seats, it’s clearly the winner. For shorter routes or when special pricing applies, two economy seats may offer better value or flexibility.
The Business Class consideration
Business Class with fully reclining seats (often 20-30″ wide in lie-flat mode) solves all space issues but runs well beyond economy budgets.
However, always compare business-class sale fares against Premium Economy—occasionally they fall within surprising range, especially on competitive routes. If budget allows even marginally, Business is the obvious choice for tall or plus-size travelers on ultra-long routes.

Questions? Answers.
Is there a rule for minimum airline seat size?
No. As of , the FAA has not set minimum seat dimensions; its focus has been evacuation safety, not comfort.
Is Premium Economy worth it for tall travelers?
Often yes on 10–16 hour Asia legs. Premium Economy typically offers 38-42″ pitch (Japan Airlines: 42″ × 19″; ANA: 38″ × 19″; Singapore Airlines: 38″ × 19″) versus 30-35″ in economy. Compare the incremental cost against flight duration using a cost-per-inch-per-hour calculation. Expect Premium Economy to cost roughly double economy fare.
Can I pre-buy an empty seat next to me internationally?
Sometimes: Etihad sells Neighbour-Free in advance; Air New Zealand offers Twin Seat; KLM allows adjacent seat purchase at ~75% fare. Emirates sells adjoining seats at the airport if available. Terms and availability vary.
Are A350 seats always 18 inches?
Airbus markets approximately 18-inch economy seats, but operator configuration varies. Singapore Airlines consistently delivers 18-19″ on A350s; other carriers may differ. Verify your exact flight and subfleet via the airline’s seat map.
What about seat choice for very broad shoulders?
Target Singapore Airlines A330-300 (19″), JAL 777-300ER (19″), or other A350/A330 configurations (18″) for width. Consider aisle seats for shoulder flare. Investigate Premium Economy where width typically increases to 18.5-19.5 inches.
Does buying two seats affect boarding or upgrades?
Policies vary—some frequent-flyer programs don’t allow upgrades on extra seat tickets. Check your airline’s terms before purchase.
