Terrible. No customer service, no food, no drinks on a 6 hour premier economy booking.

Short flight, but no drink/snack service. The flights both going and coming were delayed.

Much better than Spirit. I was please by the easy fast check in and boarding

Check-in and in-flight staff were better than average. The seat was a fair size but too hard and not enough padding. The cushion/pillow provided is poor (thin and seems to be disposable ,it provides no effective cushioning or support). Food was OK-ish but no choice of inflight snacks and no easy place to get drinks other than water (I could ask for juice by intruding into the staff area at the back of the plane) Entertainment was very good actually. Overall better than I expected from a US-based airline (sorry!) but compared to ANA or Singapore it was so-so. (I live in Japan so they are my comparative airlines)

Everything was on time Will use united again for sure

Plane outlets in my row not working to charge phone. Staff response was, well it should be. Plug into seed for volume not working well. Had to find the sweet spot for plug in or it would shut off and on.

Wifi took a while to kick in and we had a maintenance issue that took over 40 mins at the gate in Washington before pulling back

Fine not above and beyond as I had a connection that was delayed due to maintenance

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

Terrible. Our first time back on United for 10 years, the seats in Polaris class are small and uncomfortable. They have squished too many people in to get more $$$. The staff are not friendly and not wanting to accommodate. I asked for two salads rather than a main meal and was advised no we wont do that. Then asked what I would like for breakfast and given something else anyway. I will not be flying United International anytime soon.
