Contactless is a good question. That is the way I would expect to be able to pay, but it's daft they don't take cash. I just rejected a number of bookings in favour of SWISS and easyJet, simply because they were cheaper and provide better service!! Never thought I'd see myself write that about easyJet! Additionally, easyJet have an offer whereby if you pay in advance and buy a voucher you can save 20% on inflight BoB purchases. Way to go!!
