There was a engine problem, so we had to deboard and wait on a new plane but that just happens sometimes, and crew was very efficient and nice.

There was a engine problem, so we had to deboard and wait on a new plane but that just happens sometimes, and crew was very efficient and nice.

There isn't any food on that short flight. The plane had to be de-iced but it wasn't much dela

Alaska is always a great airline, friendly, clean and usually on time.

The plan from Everette to Phoenix was very dirty - the seats were grimy and the floors were filthy. I was very uncomfortable with the state of the airplane, but the staff and crew were excellent.

Friendly crew and super clean cabin. 💺 are comfortable as well. I love the ambient blue lighting.

One of the flight attendant was very rude and not helpful. The others were good. Also seats were dirty with food bags left on the seats. Looks like the plane wasn’t clean before we boarded.

unfortunately had mechanical issues and had to switch planes. the obnoxious drunk guy in the furthest back seat could have been quieter and not dropped so many f bombs.

A review system on Kayak that would allow “NA” (Not Applicable) as an answer. For example, if food wasn’t ordered, I cannot say how good it might or might not have been.

Couldn’t plug in the computer to the electrical plug underneath the seat. Should accommodate a computer power line.

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 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.

Flight did not have seat back entertainment and the wifi was iffy.

Pretty standard flight. Delta has a good selection of movies.

The WiFi has been awful on my last few Delta Air Lines flights.

The seats are uncomfortable, feels like a small seat pad on plywood.

The seats are uncomfortable and there was no power to recharge a phone.

Flight heavily delayed. No food available despite purchasing an upgrade. No in cabin service.

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?

Overall good. Tight connection in DFW because of gate unavailability upon landing.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

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.

I love to flight american however my carry on had to be sent with regular luggage and it was broken. Don't appreciate that. If when I buy a ticket says I can take a carry on and a hand item there should be space for mwsy stuff and not be basically forced to send the item even if it's at no charge. A.A. needs to work on that. Everything else excellent.

Deparature was late, which is annoying but the arrival was fine and the baggage came early.

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.

Flight departed on time and arrived a bit early. Can’t go wrong with that! And makes a travel experience go so well

WiFi wasn’t working on the flight, several delays and gate changes, ended up taking off 3 hrs later
