I didntnlike anything waste of 600 dollars. First class with Alaska for international person is like under the plane where we keep our suit cases.

Overall good. Good communication from the captain on delay, cozy seats, nice staff, and a perfect landing.

The plane was clean. The flight crew was friendly and helpful. The flight was smooth and the pilots kept everyone informed of our status, etc. It was my first flight on Alaska Airlines and it was great. I'll be choosing them again in the future.

On time boarding, plenty of overhead baggage space even for Group F, on time departure / arrival.

Like - Staff was GREAT. Friendly, efficient, kind. Dislike - nothing at all I'll be flying Alaska again in a couple of weeks - long distance.

i liked that all seats had usb ports and a plug

Good but a boarding pass for my return flight was not sent to me.

Not sure why the counter agent's couldn't have helped us with our flight change and only gave us a number to reservations. I thought their job was customer service, not "call this number"

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

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.

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?

Finding the gate was very confusing. Our boarding pass listed one gate and the staff verbally told us a different gate.

Plenty of overhead space but forced to check my carry-ons both legs

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks

It was as expected for such a short flight. No complaints

The departing flight from Newark to Charlotte was fine. It was the returning flight from Charlotte to Newark that was awful. We had scheduled an 8:35pm return flight time. We got delayed TEN times all the way to 5am in the morning! We were told over 4 different excuses as to why the flight kept getting delayed. First it was the flight crew needed to rest, then it was something technical with the plane, then it was something with air traffic control, and finally it was because they couldn’t find a captain and had to wait until the morning so the captain could get some rest. It was terrible sleeping overnight in the airport. They offered a $12 meal voucher. That was it! And the only place open in the middle of the night was Dunkin’ Donuts who didn’t even accept the voucher. They should have cancelled the flight much earlier on in the evening instead of just stringing us along hour by hour with more delays. Not professional and unacceptable. There was no refund for inconvenience. I probably will not be flying American Airlines again.

This leg they tried and did well with what they had to work from.

No food, no entertainment. But the flight was really short so maybe they had to skip drinks. I was able to board early ONLY because I am old and decrepit and they let me pre-board. I RESENT your dumping us into category 9 if we do not pay up. And when I paid for a seat I was STILL given 9. The pre-boarding helps. THIS flight was exceptionally smooth, please congratulate the pilots.

On time (actually a little early). Was a good and short flight!

Great - quick boarding and landed early with an available gate.

On time, smooth, luggage was out fast at the end of the flight. About perfect.
