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

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.

Easy boarding, good staff, comfortable seats, easy ride. Also, friendly passengers!

I don't know what it is. But it seems that flights from Ontario to Seattle are always delayed. This one was delayed 3 hours. I guess I should just expect it from now on.

Your seats are too crowded! and you don't serve full meals on this 5 hour flight? Just rake in the profits.

FLL to SEA delayed one hour due to mechanical issue. Had to return to gate from runway.

Sat next to a large person so I had to share some of my seat space with them.

I’m highly satisfied with Alaska over other airline experiences however the wifi kept kicking me off and the service was intermittent. I kept having to fool with it to get it to work.

As expected cyst service up front was very good we needed assistance at the gates and they were very accommodating

Indigo screens for passengers would have been nice but the free WiFi was nice

Delta was great the entertainment was outdated.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

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

My husband is very tall and we generally fly Delta Comfort. We used our companion benefit, and our seats were coach and extremely uncomfortable........ horrid even

My seat had no padding, it was literally plywood with a plastic cover. I could not change seats on my 10 hour flight. My excitement for this trip helped me deal with the pain.

The flight was great. The crew were a little terse about the size of my bag. It fit fine.

Screen didn’t play movies, do I was pretty boated the entire flight.

It was very cold because the air conditioner was on high power, and my son got sick.

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

Delta is one of the best airlines I have flown

Flight delayed about 2 hrs so it made it a VERY late night

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

Never happened, because of the first delayed flight I lost the connection and had to wait overnight and take two flights to reach my destination.
