Fine except from Chicago to moline three different gate changes and flight times

When booking, the connection times seem fine. But in reality, my two connections were cut short by the first leg being delayed due to issues at the destination (too much traffic going into SFO, ORD) and it became extremely stressful.

Promised internet. Tried for nine hours to log in, no way. I tried the free option, I tried the paid option, I tried restarting my phone.. several times! Very aggrevating as I was trying to keep up with an emregency medial issue with my dad, but could not because the promised service was not available.

I had bad experience with United airline. No live rep, they only have AI that respond to customers concern

Flight and crew were great. Need more legroom and do not allow seats to recline.

We arrived to Chicago nearly 30 minutes early, which was great, but then was on the ground for over an hour because the gate was not available. The issue I had was the pilot estimation was frustrating. First he said he was informed it would be 20 minutes but he said "it will probably be more like 10 minutes". After 30 minutes he came back on the comm and said it would be another 10 minutes, maybe 20. I understand he was only giving estimates but he also layered in his own gut feel. We were never told why we didn't have a gate even after our scheduled entry.

Just sat on the run way after we arrived early

The Code Share with Air Canada was not very streamlined. I had to check in at airport (not online) on the outbound and return flights

Stored my cloth purse under seat in front off me as instructed. When I retrieved it, half of it was soaked, along with everything inside it. I don’t really know how that could have been prevented because the area did not look wet, but I was not happy about it.

Phx - ORD was nice 737 with starlink and the ORD - grr was ancient bare bones airbus with not even a power port lol
