About TW
TW operates as a South Korean low-cost carrier built around Seoul's Incheon Airport (ICN), which anchors 29 of its 132 non-stop routes. The network is heavily concentrated in Northeast and Southeast Asia — Korea alone accounts for 70 routes, with Japan at 19 and Vietnam and Taiwan each pulling 8. What makes TW interesting is that its reach isn't purely regional. The BCN-ICN run clocks in at 9,594 km, which tells you this isn't just a hop-around carrier. Total network span sits at 340,114 km across 42 airports, which is a serious footprint for a budget-positioned airline.
Why fly TW?
The honest case for TW starts with the route map. If you're positioning through ICN to hit Japan, Taiwan, or Vietnam, TW can slot neatly into a multi-country Asia trip at low-cost prices. Daegu (TAE) and Busan (PUS) are useful secondary hubs if you want to skip Seoul entirely and fly direct from regional Korean cities — that saves you a domestic connection and real money. The China coverage adds five routes that budget travelers often struggle to price competitively on full-service carriers. And that Barcelona route? If you can find TW positioning on BCN-ICN at the right fare class, you're looking at a long-haul low-cost option that not many carriers in this space can match from Europe into Korea.

Tips for booking TW
Book directly through TW's site and watch the fare class carefully — base fares on low-cost carriers like this strip out almost everything, so factor in baggage fees before you assume it's cheaper than a legacy option. ICN is a well-connected hub, but Jeju (CJU) routes at 9 are seasonal-heavy, so confirm schedules if you're planning around shoulder periods. If you're routing through TAE or PUS rather than ICN, ground transfer options are more limited, so build in buffer time. First-time flyers should check the carry-on size rules — Korean LCCs tend to enforce these more strictly than European carriers do.
