*see UPDATE below* British Airways together with their Oneworld partner Qatar Airways offer an alternative option to famous Thai destination Krabi. You would have to be flexible though as return flights from various European origins are available in November 2017. Roundtrip tickets are now available already for €407 with two layovers in London and Doha. (Except the cheapest solution from Italy, Zurich also from Germany or London). Apart this look for flights departing from main airports in France, Ireland also from Amsterdam, Brussels, Stockholm, Lisbon or Budapest..Some of the flights may require long layover also airport change in the UK. This is good option to end your trip in London just make sure you choose proper routing..
