I booked a flight for june 2020 to thailand .even paid extra for full flex insurance .what a mistake .have tried to book a flight for November 2021 using voucher and the website just keeps refusing me .have spoke to customer care by email and they just kept going round in circles and basically doing nothing .spoke to them by phone they said that yes my voucher was valid but they would have to get somebody to ring me back to resolve problem .nobody ever rang back .same answer when rang again .would advise everybody to forget last minute .com but if can't then definitely refuse to pay extra for full flex insurance .
