My flight from Chicago was good, but checking in was more difficult than any other airline I've flown. First the app didn't work to check-in which wasn't a big deal, but then the kiosk wouldn't let you pay for bags. This meant standing in 2 separate lines and some confusion as nobody could help with the issue.
Flying out of Mexico was a disaster. It took over an hour to get boarding passes and check bags. First we stood in line and got to the front only to be told we had to go to a separate line to pay for bags. Then after we paid for the bags, went to the line we were sent to only to get to the front and it not accept our information. The man working talked to somebody in a separate area and told us not to stand in line just to step to a specific counter number. We got to the counter and the lady got mad and tried to send us and another couple who were sent at the same time to the back of another line, luckily the same man helped again and somebody helped us. This was the longest it's ever taken me to check-in ever. Then when I got on the plane the flight attendant Alejandra told me there wasn't space for my carry-on and when I asked her what I should do she looked at me like I was stupid and turned her head, so I had to wait for another attendant to help me. When it came time for take off the air conditioner started leaking on the passenger in the middle Alejandra came and gave her a paper towel and didn't even offer to move her even though there were multiple empty seats. After we got in the air and it was still leaking another attendant moved the lady who was having water leaked on her.
