Bangkok to London Flights (BKK - LHR)


Say “wai jur gan” (see you again) to the City of Angels and get ready to say hello to the Big Smoke when you catch your flight from Bangkok to London.

After taking in sights like Wat Pho, the Grand Palace, Asiatique and Siam Paragon mall, it’s time to sightsee at hotspots like Buckingham Palace, Harrods, Westminster Abbey and the UK’s Houses of Parliament.

Switch pad Thai noodles and tom yam (a spicy sour soup) for pies and mashed potato and fish and chips. Exchange your Thai baht (THB) for pounds Sterling (GBP).

Whereas Bangkok is hot and humid for most of the year, the weather in London can be changeable, with four distinct seasons. Don’t forget to pack warm clothes, especially if travelling during winter.


In 1976, Bangkok was Finnair’s first Asian destination. Although we have since expanded to offer many other routes between Europe and Asia, our Bangkok flights remain popular.
