Airlines Checking Onward Tickets on London → Bangkok
When flying one-way from London (LHR / LGW) to Bangkok (BKK), airline check-in agents query IATA Timatic to verify entry compliance for Thailand. Because carriers face hefty fines and mandatory return-transport costs if a passenger is refused entry at BKK, one-way travelers without a residence permit or long-term visa are required to present a confirmed outbound flight reservation with a verifiable 6-character PNR code.

Bangkok (BKK) Immigration & Arrival Card Rules
Long-haul carriers from the UK face steep repatriation costs if Thai immigration refuses entry, so check-in agents at LHR/LGW require a verifiable onward flight PNR alongside your Thailand TDAC. Standard delivery takes up to 14 hours; Instant delivery arrives in 2–20 minutes.
Required Arrival Documentation: Thailand TDAC (Thailand Digital Arrival Card). Always ensure the departure date on your onward flight reservation falls strictly within the initial visa-free or Visa on Arrival window granted by Thailand, even if you plan to apply for an in-country visa extension later.
