Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

After arriving in Chicago, we were taxiing for 1.5 hours with infrequent and untruthful updates about the amount of time it would take to arrive at the gate. Minimally, the team could have provided timing expectations that were more truthful, especially one their original expectations were not met.

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

Staff was rude. Didn’t give water for 2 hours. Worst service

Never nice, United Express partners always do an amazing job.

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

I bought internet for the flight. Don’t waste your money. I wasn’t able to download a 1 Mb file from Google Docs during a 3-4 hr period. You can only use WhatsApp and email if you are willing to wait.

The flight was on time and the crew were great.

I was forced to gate check my carry on luggage. Somehow it did not arrive at my destination. I still have yet to receive my bag r days after arrival.

Boarding area is a mess. Lines not bounded and gate area too small. Food options (on this specific flight) were poor and you couldn’t pick part of it since it was like a mash of chicken and other unrecognisable stuff. Comfort of seats along with child noise made it difficult to get a good sleep. Last, the flight attendant that served my aisle was rude (others seemed fine) towards me and others.
