On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

I love the free wifi and headrest screens. I would consider Delta even more because of this but the seats aren't so great. The snacks aren't very good in my opinion. I bought a Bloody Mary and that was great! So just be comfortable with better snacks and the airline world will be yours.

Temperature in the plane was quite warm for the entire flight - actually just outright hot making for an unoleay4 hours. Crew either couldn’t or wouldn’t do anything about it. No acknowledgement or apology. All passengers were commenting on how hot it was.

How about not delaying a red eye flight by 3 hours and causing a chain reaction of missed connecting flights

First class? Seriously? We got a wider seat and a little extra legroom. The plane didn’t even have TV’s. Not a huge deal, but there was nothing first class about this except the price tag.

I wouldn't say I liked being forced to check my small roller bag at the gate; too many people had bags and were in a higher boarding group.

Boarding started almost 20 minutes late with no explanation. Then the take off was delayed by 15 minutes with no update or explanation from the captain which was very stressful because I had a connecting flight with a very short layover. The The flight tracker on the screen at my seat was for a different flight and the QR code for the menu did not work. I asked for Sun Chips which were shown as harvest cheddar flavor on the website but the ones they gave me were salsa and I'm allergic to tomatoes and I couldn't eat them. The flight to Tulsa was okay but there was no Wi-Fi or entertainment on board which would have been nice to know

715PM departure was 2.5 hours late. Received hotel & food voucher but after we already booked a room. Entire team just seemed like they were 2-3 steps behind in execution, and notifcations.

I love the food options, I don’t mind paying an extra $10-$12 for sandwiches, fruit, cheese, and crackers, and such. I’m glad they offer it!

On time departure and early arrival. Kind and professional service from flight crew

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

they made me check my carryon. There was space in the overhead bins.

The plane was delayed 2 hours. The wifi did not work. The seat in first class was not comfortable because the bottom felt like it lost all of its padding. And I did not like when the flight attendant made me wait at my seat to use the bathroom and didn't tell me why. If there were too many people using the 1st Class bathroom, she should have told me to go in the back, coach bathrooms. I guess I have to feel fortunate that they found 2 local pilots to still fly the plane tonight after the original pilots ended up at an airport 60 miles away due to high winds.

The crew were really great, but the 4 hour delay in small chunks was the worst.

Just a crappy airline. The same every time. You feel you are a cow on a farm. You are being being whipped and pulled.

Wasn’t very crowded. Seamless processes. No issues traveling with two little kids.

My interaction with the flight attendent Eve was horrible. I was seated in 3F and was blown away watching her repeatedly skip me as she took other customer orders for lunch...she took the customer next to me but skipped me, then took everyone's order around me (in front of and behind me) . After she had taken every customer's orders to include those behind me, she came to me and said we are out of everything except one last item. I was mortified, in that, I am a 1k flyer, had pre-ordered AND as an African American could only assume why she repeatedly skipped me...mortified. no words

The Flight was good, pilot seemed very skillful. My wheel chair sister who could barely walk was allotted the second last seat in the aircraft, with great difficulty she managed to reach on her seat, as she required attendance we were given separate seat, even on request no one cared, so much so there were single passengers who were given twin seats. May not be taken as complaint but a reminder to the checkin staff to keep in mind in future the allottment of wheel chair passengers seats.

Almost 2 hour delay in boarding with all standing ready to board at original time. No explanation given.

787-9 Transcon from IAD-LAX FYI no meals in premium plus, not considered Premium - seats are wonderful https://www.united.com/ual/en/us/fly/travel/inflight/premium-services.html Horrible handling of delayed flight
