Eight airports show up repeatedly in the verified record as poor places to spend a long layover: Orlando, Dallas Fort Worth, Newark, Atlanta, Chicago O’Hare, Lisbon, Tunis Carthage, and Hanoi Noi Bai. Each has a documented failure mode — scarce charging and seating, dated terminals, security logjams, or infrastructure stretched past capacity.
Tunis Carthage ranks last of 279 airports in the 2026 AirHelp Score, with a 5.50. No single ranking covers all eight, so treat any “worst airports” list as method-dependent.
A layover is the one part of a trip you don’t choose. The routing is set by schedule and fare, so the terminal you’re stuck in for six hours is the consequence of a booking decision you already made — and the only thing still under your control is how well you’ve prepared for it.
That’s why “worst airports for layovers” lists are so popular and so unreliable.
Each one defines worst differently, and the definitions don’t travel. A hub can sit at the top of one ranking and be missing from another entirely.
This piece takes eight airports with documented layover problems — five in the U.S., plus Lisbon, Tunis Carthage, and Hanoi Noi Bai — and puts them side by side under one stated lens. It also shows you where the evidence runs out, because in several cases it does.
At a glance
- Orlando International (MCO) — the seating and charging problem
- Dallas Fort Worth International (DFW) — power access as the weak point
- Newark Liberty International (EWR) — delays and dated terminals
- Hartsfield-Jackson Atlanta (ATL) — the airport you can’t easily leave
- Chicago O’Hare (ORD) — congestion on the ground
- Lisbon Humberto Delgado (LIS) — Europe’s lowest-ranked major hub for 2026
- Tunis Carthage (TUN) — the global bottom of the 2026 field
- Noi Bai International (HAN) — capacity outrun by tourism demand
How “worst airports for layovers” gets defined
Three yardsticks dominate the coverage, and they don’t agree with each other.
The AirHelp Score 2026 is a composite. On-time performance carries 60% of the weight, passenger experience 20%, and facilities and comfort 20%. AirHelp evaluated 279 airports across 76 countries over a window running May 1, 2025, through April 30, 2026, drawing on nearly 14,300 unique airport ratings from travelers in more than 68 countries.
MarketWatch took a narrower route, scoring amenities and infrastructure across 29 major U.S. airports and publishing on November 28, 2023, with passenger-volume measures that include calendar year 2022.
A third group of outlets ranks almost entirely on delays and compensation claims, which tells you nothing about whether you’ll find a seat or an outlet.
Here’s the detail that should change how you read any of these lists: AirHelp counts an arrival as on time if it lands within 15 minutes of schedule. A flight can be counted as punctual by that rule and still swallow the bulk of a short connection.
No single methodology covers all eight airports below. That’s the honest limitation, and it’s why what follows is a comparison of documented failure modes rather than a ranking.

The eight hubs, and what’s documented at each
The numbering is a reading order, not a ranking. Each airport appears because a named ranking body or official source documented a specific failure mode — not because it scored worse than the one above it.
1. Orlando International (MCO) — the seating and charging problem
Orlando posted the lowest seat-availability rating of the 29 major U.S. airports in MarketWatch’s layover study.
The same study tied Orlando with Newark for the lowest mid-priced-shop rating. Its documented shortcomings are specific: cluttered public spaces, restricted charging access, and not enough seats.
On a four-hour connection that stops being a comfort complaint and becomes a logistics problem. You end up circling the concourse hunting for an outlet instead of sitting down.
2. Dallas Fort Worth International (DFW) — power access as the weak point
Limited accessible power and charging infrastructure is the documented reason DFW keeps placing low in layover-quality assessments.
It’s the same study and the same category of failure as Orlando’s, but the mechanism is narrower. The complaint isn’t that DFW is unpleasant to be in — it’s that the power access isn’t there when you need it.
For anyone planning to work through a long connection, that single variable decides whether the layover is usable or wasted.
3. Newark Liberty International (EWR) — delays and dated terminals
Newark tied with Orlando for the lowest mid-priced-shop rating in the MarketWatch study.
Multiple reports keep circling the same three complaints: outdated terminal facilities, cancellation rates, and significant delays. The retrieved material states no unified delay score for the airport, so the operational side of the picture stays qualitative rather than numeric.
In practice, a long layover at Newark stacks two risks. You get a dated terminal to sit in, and a higher chance the connection itself moves.
4. Hartsfield-Jackson Atlanta (ATL) — the airport you can’t easily leave
Atlanta’s security wait times and passenger volume make leaving and re-entering the airport genuinely difficult.
This is a different kind of failure. Atlanta’s problem isn’t the terminal — it’s the exit-and-re-enter test, the thing you’d actually want to attempt on a seven-hour layover.
Long security lines plus heavy passenger volume change the arithmetic: a quick trip into the city can cost more time in the queue than it returns. No comparable numeric score for Atlanta appears in the retrieved material.
5. Chicago O’Hare (ORD) — congestion on the ground
Congested terminals, limited seating, and high delay volume put O’Hare among the worst U.S. hubs for layovers.
O’Hare shows up in both the MarketWatch study and in operational coverage, which is why it lands here — the amenity problem and the reliability problem overlap rather than sitting in separate columns.
The retrieved text states no airport-specific overall numeric score for O’Hare. The pattern of complaints carries the claim, not a single figure.
6. Lisbon Humberto Delgado (LIS) — Europe’s lowest-ranked major hub for 2026
Lisbon is identified as Europe’s lowest-ranked major airport for 2026.
The cause is volume. Passenger numbers have strained infrastructure and driven delays, and no airport-specific score for Lisbon appears in the retrieved text — the ranking position is the claim, not a number.
For a traveler connecting through, the risk profile is congestion rather than amenity failure. That’s a harder problem to pack for.
7. Tunis Carthage (TUN) — the global bottom of the 2026 field
Tunis Carthage scored 5.50 and ranked last among the 279 airports AirHelp evaluated for 2026.
The specific failure is punctuality: Tunis posted the weakest on-time departure performance in the entire field. That matters more than it sounds — AirHelp’s composite leans hard on punctuality, so a weak departure record can sink a hub no matter how its terminal feels.
A hub can have a perfectly reasonable terminal and still sink on departures alone.
8. Noi Bai International (HAN) — capacity outrun by tourism demand
Vietnam’s tourism demand has grown faster than airport capacity or operational efficiency could absorb, leaving Noi Bai under rising strain.
Hanoi’s inclusion is a reminder that the layover problem isn’t a Western one. The documented issue is capacity pressure rather than a specific amenity failure, and no comparable numeric score appears in the retrieved material.
For a traveler routing through Southeast Asia, the practical read is simple: the airport is absorbing more traffic than it was built for.
Here’s the same eight, side by side, with the body behind each claim and what that body actually measures.
| Airport | Region | Ranking body behind the claim | What that body measures | Reported figure or score | Specific documented failure mode | Measurement date |
|---|---|---|---|---|---|---|
| Orlando International (MCO) | United States | MarketWatch | Layover amenities, infrastructure, and service across 29 major U.S. airports | Lowest seat-availability rating; no overall numeric score stated | Low seat availability, restricted charging access, cluttered public spaces | Published November 28, 2023; passenger data include 2022 |
| Dallas Fort Worth International (DFW) | United States | MarketWatch | Same U.S. layover comparison | No airport-specific numeric score stated | Limited accessible power and charging infrastructure | Published November 28, 2023; passenger data include 2022 |
| Newark Liberty International (EWR) | United States | MarketWatch and other cited reports | MarketWatch measures layover amenities; other reports emphasize operations | Tied with Orlando for lowest mid-priced-shop rating | Outdated terminals, cancellations, significant delays | MarketWatch published November 28, 2023; operational claims undated |
| Hartsfield-Jackson Atlanta (ATL) | United States | Qualitative/operational coverage | Security waits and passenger-volume logistics, not a unified layover score | No comparable numeric score stated | Long security waits and high volume make leaving and re-entering difficult | No single measurement date stated |
| Chicago O’Hare (ORD) | United States | MarketWatch and qualitative/operational coverage | Layover amenities and infrastructure, plus congestion and delay reporting | No airport-specific numeric score stated | Congested terminals, limited seating, high delay volume | MarketWatch published November 28, 2023; operational data undated |
| Lisbon Humberto Delgado (LIS) | Europe | AirHelp Score 2026 | On-time performance, passenger experience, facilities and comfort | Europe’s lowest-ranked major airport for 2026; no score in retrieved text | Infrastructure strain and delays tied to passenger volume | AirHelp window: May 1, 2025-April 30, 2026 |
| Tunis Carthage (TUN) | North Africa | AirHelp Score 2026 | On-time performance, passenger experience, facilities and comfort | Global bottom rank among 279 airports; score 5.50 | Weakest on-time departure performance in the AirHelp field | AirHelp window: May 1, 2025-April 30, 2026 |
| Noi Bai International (HAN) | Southeast Asia | Infrastructure and operational reporting | Capacity and operational pressure, not a unified layover score | No comparable numeric score stated | Infrastructure strained as tourism demand outpaced capacity | No single measurement date stated |

How we picked
An airport earned a place here only where a named ranking body or official source documented a specific failure mode — no vague “one of the worst” labels. MarketWatch’s 29-airport U.S. study and AirHelp’s global 2026 score supply most of the record; Lisbon Airport and Noi Bai’s own pages cover entry rules. The eight rows are a count of documented offenders, not an ordinal ranking.
What this means for you
If you’re planning to leave the airport on a long layover, the documentation test matters more than any queue-time estimate. Lisbon Airport states that third-country nationals must present a passport and may need a visa depending on nationality and stay length. Noi Bai requires a valid passport plus a visa or qualifying approval documentation to enter Vietnam, and staying inside the international transit area is not the same as entering the country.
No comparable re-entry timing exists for Lisbon, Tunis, and Hanoi in the official material reviewed, so plan around the paperwork rather than a stopwatch.
And a distinction worth holding onto: lounges are not beds. Where an airport offers no sleeping infrastructure, you’re buying a meal, a shower, and a seat — nothing more. If a long layover genuinely needs sleep, confirm the airport sells a rest product before assuming a lounge covers it.
And when the next “worst airport” headline lands, check which body produced it and what that body measures. A delay-only ranking says nothing about whether you’ll find a seat or an outlet. Most of the hubs above remain perfectly reasonable to connect through — the ones that punish you are the ones where you assumed the terminal would cover the gap.
Reporting by
Key terms
- Third-country national
- A third-country national is a traveler who does not hold citizenship of the country whose border they are crossing. In the Lisbon case, that status is what triggers Portugal’s requirement to present a passport and, depending on nationality and length of stay, possibly a visa. It is the term that decides whether a long stop at Lisbon can include leaving the airport, since documentation applies to entry rather than to the layover itself.
- International transit area
- The international transit area is the part of a terminal that sits past security but short of a country’s immigration entry point, where connecting passengers wait without formally entering. It exists because international transfers are handled separately from arrivals, and the boundary determines whether a traveler needs entry documents at all. For the airports in this comparison, that distinction decides whether a six-hour stop is a chance to see the city or simply a longer wait in the terminal.
- On-time performance
- On-time performance is the share of an airline’s or airport’s flights that operate within a set tolerance of their published schedule. AirHelp’s 2026 composite counts an arrival as on time if it lands no more than 15 minutes late, and gives that measure 60% of the total score. Because the same rule is applied across the whole field, it is the measure that lets one index compare airports as far apart as Tunis Carthage and Lisbon — something an amenity survey could not do.
Questions? Answers.
What are the 10 most stressful airports in the US?
No verified list of ten appears in the record reviewed here. The closest documented U.S. comparison is MarketWatch’s study of 29 major airports, in which Orlando posted the lowest seat-availability rating and tied with Newark for the lowest mid-priced-shop rating. Those two are the only U.S. hubs with a specific, sourced shortfall in that study.
Do airports pay to appear in rankings like the AirHelp Score?
The retrieved AirHelp methodology does not establish that airports pay, participate, or self-submit to obtain a ranking. AirHelp builds the score itself from its own flight database, facility assessments, and passenger ratings. MarketWatch’s study is an editorial analysis drawing on public and commercial inputs. Neither shows paid inclusion.
Why do different ‘worst airport’ lists disagree with each other?
Because they measure different things. AirHelp weights on-time performance at 60%, passenger experience at 20%, and facilities and comfort at 20%; MarketWatch scored amenities and infrastructure across 29 U.S. airports; other outlets rank almost purely on delays. The retrieved MarketWatch text states no airport-specific overall numeric score for Orlando, Dallas Fort Worth, or Chicago O’Hare, and no comparable official layover metric could be verified for Dubai or Frankfurt at all. The eight rows here are a documented comparison, not an ordinal ranking.
Why are Dubai and Frankfurt left out of the comparison?
The material reviewed turned up no airport-operator or filing-based layover-quality data for either Dubai International or Frankfurt Airport. A commercial lounge page mentions sleep facilities at both, but that is not an airport score or an operating filing. Without a comparable official metric, neither hub earns a row.
