Reply To: Producing Amex card that paid taxes on 2 4 1 booking

[Matt]

I have twice been asked for the credit card I had booked with (once on Sri Lankan, once I can’t remember the airline but not in Europe) – both times were several years ago. It’s not something I would worry about at all with BA. At worst you’d have to pay the cost again on your card and get a refund to the card you used originally, you certainly wouldn’t have to pay an inflated cost.
