Good air fare deal – £1,346 London to Seoul in Business Class with Air France and KLM
Links on Head for Points may support the site by paying a commission. See here for all partner links.
Air France and KLM have launched some aggressive business class fares from London to Seoul. You can get as low as £1346 return for much of the year.
I recommend starting at klm.com because the default departure period is ‘Between now and January 2020’ so you can easily find dates where the fare is £1346.
Note that, whilst Expedia shows a lower fare of £1163, it appears to jump up to £1346 on the final payment page so you might as well book direct.
These flights need to be credited to a SkyTeam frequent flyer programme such as Flying Blue or Delta SkyMiles.
However, if you travelling from April onwards it is possible that you will also be able to credit them to Virgin Flying Club – it depends on the official start date for the new Virgin / Air France KLM joint venture.
Look at reviews of the aircraft you will be using before booking, as Air France still has some aircraft with sloping beds in Business Class. I believe that KLM is now fully flat on all aircraft.
Your best option to maximise your miles when paying is American Express Preferred Rewards Gold. This offers double points – 2 per £1 – when you when you book flight tickets directly with an airline.
