Christmas isn't Christmas without at least two emails from low-cost airlines inviting me to give the gift of travel – in the shape of a flight voucher. "Beat the last-minute rush with a gift that takes them places," advises Ryanair. Rival Wizz Air urges: "Skip the guesswork and surprise your loved ones with a Wizz gift voucher. They choose the destination – from twinkling Christmas markets to sunny winter escapes – and you get all the hugs."
