Because of Covid, Air France are currently offering free refunds on basic flights, for travel before 30 June 2022, if booked before 1 March 2022. If you don't want to use the flight, because of Covid, or we don't make the final, or you get cheap Ryanair ones or whatever, you can cancel them. You get a voucher which is valid for a year but can be exchanged for a proper refund whenever you like. At least that's what it says on the website and they confirmed on chat. Check for yourselves but worth having just in case.
Currently about £190 to fly out to Paris Thursday evening, back Sunday evening.
