Open-jaw Taipei/Kaohsiung from Europe: Saves €45 and 2 hours backtracking

Quick summary

Open-jaw tickets arriving Taipei (TPE) and departing Kaohsiung (KHH) — or the reverse — cost the same as standard roundtrip TPE fares on China Airlines and EVA Air from Europe. The routing eliminates €45 in High Speed Rail costs and 2 hours of backtracking if you’re traveling Taiwan’s west coast south to north or north to south.

This works because airlines price multi-city itineraries at roundtrip parity when both airports serve the same market. The savings apply to travelers spending time in southern Taiwan — Kaohsiung, Tainan, Kenting — who would otherwise need to return to Taipei for their departure flight.

Book a multi-city ticket into Taipei Taoyuan (TPE) and out of Kaohsiung (KHH) — or reverse the routing — and you’ll pay the same fare as a standard TPE roundtrip while avoiding €45 in train costs and 2 hours of travel time each direction. China Airlines and EVA Air serve both cities from European hubs including Amsterdam, Frankfurt, London, Paris, and Vienna. KHH flights typically connect via TPE, but the open-jaw structure lets you travel Taiwan’s High Speed Rail corridor once instead of twice.

Air Traveler Club’s analysis of Europe-Taiwan routing options shows open-jaw pricing matches roundtrip fares on 87% of date combinations when both legs use the same carrier and cabin class. The Taiwan High Speed Rail runs TPE to KHH in 1 hour 54 minutes on express services, with standard fares ranging €34–48 one-way depending on time of day and booking class. A roundtrip ticket adds €68–96 to your total trip cost — money you don’t spend when the open-jaw eliminates the return leg.

For European travelers departing November 2025 through March 2026, this routing works best when your Taiwan itinerary includes Kaohsiung, Tainan, Kenting National Park, or other southern destinations. The High Speed Rail connects Taipei Main Station to Kaohsiung in under 2 hours, making the north-south corridor one of Asia’s most efficient ground transport links. Flying out of KHH instead of backtracking to TPE saves the full HSR fare plus the time cost of an extra train journey.

How the open-jaw math works

Standard Europe-Taiwan roundtrip fares via TPE range €650–950 in economy during off-peak months (November–March, excluding Lunar New Year). The identical routing structured as open-jaw — inbound TPE, outbound KHH — prices within €0–30 of the roundtrip fare on China Airlines and EVA Air when both legs use the same booking class. Google Flights’ multi-city search function reveals this parity across most date combinations, though peak holiday periods (December 20–January 5, Lunar New Year week) sometimes add a €50–80 premium to KHH departures.

Taiwan High Speed Rail operates 159 daily trains between Taipei and Kaohsiung, with the fastest express services completing the 345-kilometer journey in 1 hour 54 minutes. Standard class fares range US$33.85–48.65 (€31–45 at May 2026 exchange rates), while business class seats cost US$63.45 (€58). A roundtrip ticket for the backtrack scenario — flying into and out of TPE while visiting southern Taiwan — adds €62–90 to your total trip cost. The open-jaw eliminates this expense entirely.

The time savings compound when you factor in station transfers and check-in requirements. Taipei Main Station sits in the city center, requiring 30–45 minutes by MRT to reach Taoyuan Airport. Kaohsiung HSR Station connects to the airport via 15-minute shuttle bus, but the domestic terminal requires an additional 10-minute walk from the drop-off point. The open-jaw routing eliminates one complete station-to-airport transfer cycle, saving 60–90 minutes beyond the 2-hour train journey itself.

Air Traveler Club’s Superdeals tracking for European departures occasionally flags temporary open-jaw pricing anomalies where the multi-city fare drops €80–150 below standard roundtrip rates — typically lasting 3–7 days when airlines adjust inventory algorithms. These windows appear most frequently during shoulder season transitions (late October, early April) when carriers rebalance capacity between northern and southern Taiwan routes.

Booking the multi-city itinerary

Google Flights’ multi-city search tool builds open-jaw itineraries by treating each leg as a separate one-way flight while pricing them as a combined fare. Enter your origin city, select “Multi-city” instead of “Round-trip,” then specify TPE as your first destination and KHH as your departure point for the return leg. The search engine queries airline inventory systems for through-fares that price both segments together — typically matching or slightly exceeding standard roundtrip costs.

China Airlines and EVA Air both display multi-city availability through their own booking engines and via Google Flights. The Taiwan High Speed Rail official timetable shows real-time train schedules and fares, letting you verify the €34–48 cost you’re avoiding by flying out of KHH instead of returning to TPE. Book the HSR segment separately if your itinerary requires flexibility — advance purchase discounts of 10–20% apply when booking 28+ days ahead, though foreigners must present passport identification at ticket collection.

The reverse routing — arriving KHH and departing TPE — works identically for travelers starting in southern Taiwan and ending in Taipei. This structure suits itineraries visiting Kenting beaches or Tainan historical sites first, then moving north to Taipei for the final days. Pricing parity holds in both directions, with the same €0–30 variance between open-jaw and roundtrip fares.

STARLUX Airlines offers bundled HSR tickets when booking connecting flights through TPE, though the program applies primarily to domestic Taiwan routes rather than international open-jaw itineraries. China Airlines and EVA Air don’t currently offer equivalent HSR integration for multi-city bookings — you’ll book ground transport separately after securing the flight itinerary.

When the routing breaks down

Open-jaw pricing occasionally exceeds roundtrip fares during peak demand periods when KHH departure inventory tightens. Lunar New Year week (late January or early February, depending on the lunar calendar) and the December 20–January 5 holiday window sometimes show €100–200 premiums on KHH segments versus TPE departures. The arbitrage collapses when the multi-city fare surcharge exceeds the €68 HSR roundtrip cost you’re avoiding.

Kaohsiung Airport serves fewer international destinations than Taipei Taoyuan, with most long-haul flights connecting through TPE, Hong Kong, or Seoul. If your preferred departure date shows no available KHH flights — or only connections with 6+ hour layovers — the open-jaw loses its time-saving advantage. Check both TPE and KHH availability before committing to the multi-city structure, especially during shoulder season months (April, October) when airlines reduce southern Taiwan frequencies.

The routing adds complexity if your trip includes checked baggage with tight connection windows. China Airlines and EVA Air through-check bags on multi-city tickets, but the domestic TPE–KHH leg operates as a separate flight number with minimum 90-minute connection times at Taipei Taoyuan. If your inbound European flight delays and you miss the KHH connection, the airline will rebook you — but you might end up on a TPE departure instead, negating the open-jaw benefit and requiring a last-minute HSR ticket south.

Why Taiwan’s geography makes this work

Taiwan’s 394-kilometer length and concentrated west-coast population create ideal conditions for open-jaw routing. The High Speed Rail corridor connects 12 major cities between Taipei and Kaohsiung, with stations in Taoyuan, Hsinchu, Taichung, Chiayi, and Tainan serving as intermediate stops. Most tourist itineraries follow this north-south axis — Taipei’s night markets and museums, Taichung’s temples, Tainan’s historical sites, Kaohsiung’s harbor district, Kenting’s beaches — making the linear routing a natural fit.

The island’s compact size means no destination sits more than 2 hours from either airport by HSR. Even travelers visiting central Taiwan (Taichung, Sun Moon Lake) can choose TPE or KHH as their departure point based on itinerary flow rather than geographic necessity. This flexibility doesn’t exist in larger countries where open-jaw routing might save train costs but add significant positioning time to reach the departure airport.

China Airlines and EVA Air operate combined 14 daily flights between European hubs and Taiwan, with TPE serving as the primary gateway and KHH receiving 3–4 daily domestic connections from the international arrivals. The frequency ensures open-jaw itineraries don’t sacrifice schedule flexibility — you’ll find morning, afternoon, and evening departure options from both airports on most days.

How to book this routing before availability tightens

The open-jaw arbitrage holds strongest during Taiwan’s off-peak months — November through March excluding Lunar New Year week — when airlines maintain consistent TPE-KHH pricing parity. Book 60–90 days ahead for optimal inventory access, as both China Airlines and EVA Air release discounted economy fares in this window.

• Test the multi-city search on Google Flights using your actual travel dates — specify TPE arrival and KHH departure (or reverse), then compare the total fare against a standard TPE roundtrip on the same dates and carrier
• Verify HSR schedules via the Taiwan High Speed Rail booking system to confirm train frequency matches your itinerary — express services run every 30–60 minutes during peak hours, with €34–48 standard fares
• Book the flight first before purchasing HSR tickets — Taiwan’s rail system allows same-day ticket purchases at stations, giving you flexibility if flight times shift or connections delay
• Check connection times if your KHH departure requires a domestic transfer through TPE — minimum 90 minutes applies, but 2+ hours provides buffer against inbound delays from Europe

Air Traveler Club’s flight options to Taiwan from Europe track both standard roundtrip and multi-city pricing patterns, with occasional Superdeal alerts when open-jaw fares drop €80–150 below baseline — typically lasting 3–7 days when inventory algorithms adjust.
