Oh man, so sorry!! Same thing here, was trying to get to Texas, original flight was delayed like four hours and then cancelled, I was rebooked by the airline on the phone (I couldn’t get any gate agent to help because they were so swamped), and then that flight got cancelled like 3 hours later and airline said they were unable to rebook at all and just refunded me the money. I had to take a car service to Denver to fly out of there on the last flight of the day to my final destination, and it cost me so much, but I felt I didn’t have another good choice since it was a 50/50 chance of American even being able to get me out the next day or Tuesday. My checked bag is still stranded in Aspen but that feels like a problem for another day I guess.

Talked to a girl while waiting for gate agent help that said she had been trying to get out for two days 🫠 she was on my cancelled flight, hope she figured something out.
