likewise … a tad surprised, because I changed that booking probably half a dozen times (once adding an onward connection to a different destination, back to the original routing, then switching the return to leave from a co-terminal, then something else) before actually flying the original departure; during the trip I changed the return to be on a different day, and then did a co-terminal SDC for my actual return

unfortunately I also just noticed the “Book by May 26” provision that I’d forgotten about, but I can figure something out in the next few days
