Flight home was delayed multiple times, did not get home until 2am

the check-in lady at ORD was extremely rude and unprofessional. very disappointed as it was supposed to be a celebration for my wife's birthday and it really put a damper on things. if i wanted to be treated like trash, i would have flown Economy! (as opposed to business class)

My original flight was cancelled and then rebooked four hours later on a recovery flight, but I was checked in as stanby and had no seats so as a family of four we were concerned about not being seated altogether. Our flight then got delayed by another 1.5 hours and when seats were assigned at the gate, three of the four of us were together and we could get my wife closer, they offered no assistance.

I bought a ticket from Kayak. When I got to the airport, the was no ticket. I had to pay 5X to get to my destination. No response received from Kayak. I will NEVER use them again.

My wallet was stolen while I was sleeping on the plane.

Good boarding but extremely cold temperature in both flights (60 F!).

The whole plane smelled and felt old. The seats were very uncomfortable. Multiple delays. Extra fees.

Very rude gate attendants in San Francisco who didn’t let me bring my little carry on (smaller than usual size) and after boarding I realized that there still were a lot of overhead compartment space (like a full section available in some spots). That made me lose 30 minutes at my destination at 1am and it could have broken something fragile that I had in it

The most uncomfortable flight I’ve ever been on. I’m only 5,4” and barely had enough room to exist, couldn’t even fully relax my shoulders. Not sure why they bother with snacks. Half a coke and a single cookie?? Wow. Purchasable food looked gross too. Remember when airlines used to treat you like a human being?

Departed Palm Springs over an hour late because there’s only one gate, and it has always delayed by the arriving and departing flight to Toronto and the arriving flight from Vancouver.
