Over on AskReddit, there’s a thread entitled “What was a loophole that you found and exploited the hell out of?” which contained this gem about Spirit Airlines:
I coach a high school team; we recently bought airfare with Spirit airlines to take 9 students to a competition. Two of the students cancelled about a month out from the trip, and we had to replace them with two different students. Spirit airlines’ policy: no name changes. Can’t even pay a fee to change the name. The tickets are basically lost, I have to buy new tickets. Spirit’s customer service is overseas, and they plainly don’t care at all about customer service (because they don’t actually work for Spirit etc etc).
EXCEPT that Spirit airlines DOES allow passengers to correct misspellings. And these folks don’t really recognize nonsense names. So over four calls, I change the names of the cancelled students to the names of the new students, two letters at a time. No one at Spirit customer service made a note (because who would care), and no one ever notices that the “correct” names during the intermediate steps were nonsense.
