We were seated in the middle of a large group of noisy 8th graders

You sold me a $230 seat upgrade. But it was exactly the same seat as the $89 upgrade. The bait and switch seems to have become common practice.

I never received a full itinerary of my round trip. I only received the outgoing flight on Sun Country to Baltimore. Throughout my stay in the Baltimore area I kept checking for the information on my return trip to Portland, I didn't receive it in timely manner, so I booked another flight. I received the return flight information on the Alaska flight booked via your sight upon returning to my home in Oregon. The cost of my ticket on Price line was $247.27. The flight was Alaska Airline Flight 9. The confirmation number is YWHLPB. Please be advised I purchased Insurance for this flight. The reference number is UVCV4-X4TK9-INS. I respectfully request a refund for the bookings on, AS 507 and AS 1121.The confirmation number is 72058793562147. Thank you for assistance in correcting this matter.

The flight attendants are very friendly and courteous. Excellent service.

Good except for major turbulence around the Rockies. The pilot did an excellent job of controlling the plane. I wish there was a better way to get through that area next time.

It was Okay. I do appreciate the flight being on time and the happy crew.

It was a good flight, crew members were friendly. The flight was smooth and overall a great experience.

What was the reason for the flight delay? The plane was there in plenty of time!

We purchased tickets and were last to board while standby passengers were boarding before us. The WiFi wasn't working and the same thing happened on our last Alaska flight. The snack provided was vegan I wasn't going to chance eating that on a 6 hour flight incase it didn't agree with me.

The flight, boarding, and check-in experience couldn't have been a better experience. However, I ordered food ahead of time pre-flight and there was no record of that purchase, no receipt sent to my phone and the flight attendant was pretty was pretty "whatever" about it. Luckily we were able to purchase onboard but it was annoying to say the least. Especially if there would not have been other food to purchase as it's a long flight, not to add the worry of whether or not I had been charged. Otherwise, pretty good experience overall.

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

This was a 5 hour flight with no entertainment and with a snack being provided (pretzels and fruit bar), which are both high in carbs and sugar. Nuts would have been a better choice.

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

Everything was perfect except the pad at the top of the seat back. It pushes my head forward in a very uncomfortable position and it is not removable.

Good plane, crew, and flight. Boarding was a bit chaotic. Bathrooms were unacceptable. United DESPERATELY needs a new terminal at IAD.

United Airlines changed my flight 5 hours before I arrived at the airport. This messed up my entire day that I arrived in Japan.

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

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

United ground crew and pilots are friendly. The in-flight staff (flight attendants) are the worst in the world. Multiple trips, always unpleasant, combative, use implicit threats to not allow for a discussion on their decision. Authoritarian. This seems to stem from an internal corporate wide policy as I doubt that United is intentionally searching for people that are not fit for customer facing positions. I will not fly United again. Good luck fixing your business

The flight was mostly on time, smooth and deplaning was quick. Baggage was really quick at the claim. Comfort was so-so and I paid for economy plus. It was still too crowded and why was a family of 5 scattered all around the plane?
