I booked a flight from makemytrip using my credit card. I will be travelling in British Airways from India to the US. I am planning to cancel the credit card because I am leaving the country for good. What will happen if I cancel my credit card? Will I need it during the check in?
Presenting the card and running a transaction on the card are different things. I bought some show tickets a while back, changed the card, but kept the old card for ticket pickup. The company just wanted to match the numbers on the transaction to the numbers on the piece of plastic, the transaction was run at the time of purchase.
People change / lose / expire cards every day, and no airline is going to wait until departure to take your money. Just keep the old card after you cancel it.
