Bangkok to Taipei - Thai, EVA, and budget carriers NokScoot and Thai Lion cram a.
Thai Airways and EVA Air operate nonstops from Suvarnabhumi (BKK) to Taoyuan (TPE), while budget carriers Thai Lion Air and Scoot fly from Don Mueang (DMK). The flight is 3.5 hours northbound and about 3 hours 45 minutes returning. Thai AirAsia also occasionally serves this city pair from DMK. Bangkok - Taipei planning works best when transfer times and baggage rules are checked together.
Taiwanese travellers love Bangkok for food and shopping, and Thai travellers increasingly visit Taipei for night markets and Jiufen. This two-way demand keeps the corridor well-served year-round. May-June (rainy season in Bangkok, low tourist flow) and September are the cheapest booking windows. Chinese New Year and Songkran (mid-April) produce sharp spikes as both countries celebrate overlapping festivals.
Budget carrier pricing from DMK starts at around THB 2,500-4,000 one-way. EVA Air's Star Alliance connectivity and included luggage make it the premium choice at roughly double the budget fare. For travellers connecting beyond Taipei to other Taiwanese cities, EVA's Taoyuan hub advantage matters - domestic connections via UNI Air are seamless. Bangkok - Taipei spans about 2,500 km, so itinerary structure can change total travel time.
Nonstop flights take 3.5 to 4 hours. Thai Airways and EVA fly from BKK, while budget carriers (Thai Lion, Scoot) operate from DMK. There is no meaningful flight time difference between the two Bangkok airports.
May-June and September offer the lowest fares. Avoid Chinese New Year (late January-February) and Songkran (mid-April) - both create dual-peak demand that inflates pricing sharply.
BKK for Thai Airways and EVA Air (full-service, included luggage). DMK for Thai Lion and Scoot (budget fares, paid add-ons). If you are connecting beyond Taipei, EVA from BKK offers the best hub connectivity.
