JUST IN CASE YOU FORGOT DURING THE PANDEMIC HOW MUCH FUN IT IS TO DEAL WITH OUR AIRLINE MONOPSONY: Recently, I booked a last-minute ticket on Delta. I used flight credits from a pre-pandemic flight that was canceled, no new payment required. I rushed to the airport with my family, and tried to check in. No dice. I went to the counter. The man behind the counter told me that I need the credit card used to purchase the ticket. I explained that (a) I did not use a credit card to purchase the ticket, given that there was no charge; and (b) I don’t have the credit card the system is saying that I need to present (which I assume was saved in my Delta profile). Nevertheless, the Delta employee insisted that I needed to show the credit card I used to purchase the ticket. The ultimate resolution was that he had to cancel and then rebook the ticket, a process that required him to call into the Delta call center and which took almost an hour. We would have missed our flight but for a fortuitous weather delay–all because I couldn’t present the card I used to purchase the ticket, which never actually happened. I would have been mollified by an apology by Delta after I alerted them to what happened via their Twitter help handle, but nothing.
