Traveling for too many years and never asked for credit card until today when tried to check in for my DL flight tomorrow ONT-SLC-AMS-NBO. Message said to swipe at airport for BP. Ticket was bought 18 Feb 2017 on my US Citi Prestige! Credit card account closed about 6 months ago after Citi changed benefits. Since today is disaster for airlines with storms will go to counter tomorrow morning.
