How about not cancelled, but unable to make a reservation:
This is getting RIDICULOUS - now that said, all of these i was makign reservation within 18 hours of the flight. I rarely had a problem pre covid.
Yesterday - for a flight today
UA - no seats - kept checking up until time i would have had to leave for the airport (10 min ago)
DL - one seat that got me an overnight layover
WN - no seats
AA - several seats - only one FC seat available ans decent routing
July whatever when they increase flights can't come soon enough. My entire spring got cancelled and I had some time off - now, I have to pay the piper and I need to fly. GS desk has been very somber, they say they hear it daily that GS have to fly other airlines.
UGGH - sorry rant over
