I am trying to book flights. OMG I know there are more important things going on in the world but I too have a life! The payment page is telling me consistently that bank code can be only digits ?!! what are they talking about anyone? I have completed these purchases a hundred times. What have I done wrong now? So far as I can see the card details are correct. Is it a blip on their page and will I now have to trawl through it all again, purchasing for 6 of us? (and bloody online checkin is now charged)
