I usually choose Alaska Airlines over any other airline. They try the hardest to make flying a great experience.

Staff being friendly would have help since the flight was delayed, again. Folks answered questions but no one seemed happy to be working today and if showed.

Quick easy boarding. Airport was unprepared for early landing and we were waiting in the plane for 20 minutes before getting a gate.

My plane ride down landed 20 min late. Boarding at SFO was strange too. The people at the terminal were nice—but, boarding lacked direction, and was confusing . Coming back was worse—the plane was hours behind—and I barely caught the last Bart train back to San Francisco (3 min more and I would have been in trouble). It was a very stressful trip, and it didn’t need to be.

This flight was significantly affected by poor wifi connections. I couldn’t get my work done because the wifi kept dropping. Even texts were not going through. There is no seat power in premium class either. I fly a lot. Today was my 10th flight in 4 weeks. This was by far the only flight that was sub par.

WiFi connection bad. Food is really awful. Crew very nice and efficient

It was the worst experience because they delayed the flight by 2 and half hours. We were supposed to depart by 3:41 but they did the depart by 6 pm. It was so boring!!

Due to delayed flight, we missed our connecting flight as well as had to wait for 11 hours for next availaible flight. Not good experience

My experience with Alaska Airlines flights is dominated by the fact that today’s economy class is barely humane. Everyone is so tightly packed together that one cannot move an inch for the entire flight…. and if it’s a bicoastal trip, that’s almost five hours of discomfort!! And if you’re above average in height and/or weight it’s absolute hell! Moreover, still all Economy classes are basically the same across airline carriers, it doesn’t matter who you fly with.

Everything was fine within the parameters of flying full aircraft. My only small regret was that the non-meal, "snack" type food options had 90% medium to high sodium items. They looked appetizing, but many, if not most older Americans are restricted in sodium intake, so maybe one low/no sodium option would entice people to buy them. I brought my own food. The staff, on-time and aircraft quality were great, as usual for Alaska.

I was told we'd have a hot breakfast option in first class, so I chose not get a hot breakfast. It was a very strange meal, but the fresh fruit was very good quality. Service was excellent from ORD to ELP. No service from MBS to ORD, not even water. However, when flying American from FNT to ORD, which is a shorter flight, they at least pass out snacks and offer water.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

The flight was delayed instead of leaving at 11 it left at 12.20

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Good movies, iffy pay WiFi, food ok- on time though and that was great!

Awful…flight was delayed more than 12hrs, missed all connections to Fort Wayne, IN, had to get flight to another city 2 hours from my destination, flight was again delayed by 40 mins because they did not have enough fuel, again missed a connection, finally arrived in Indiana at 11pm…but before my 2 hour drive home, ay, no Five That Our Luggage Never Made On The plane and Still In Chicago

Boarding was friendly and quick. While the plane model was older with no live tv, the entertainment was full of movies and tv shows. All food was available. Pilots were very communicative with status of the flight. Flight landed on time.

The Palm Springs to Chicago O’Hare was on Time and Palm Springs airport is easier navigate. As our connection was only an approximately 50 minutes, we asked staff for insights for the Chicago airport in terms of transferring into the other terminal from which our flight left, and they were unhelpful. However, the United App was very helpful in terms of notifications and even providing directions. The Chicago to Detroit flight was significantly delayed which we all know does happen. However, there were very few updates or notifications as to why this was happening when we would actually arrive. It took nearly 30 minutes for bags to make it to baggage claim. We arrived nearly 1 hour late on a 40 minute flight.

Flight cancelled due to fog. No other flights available for 36 hours. Directed by United to book passage on another carrier, and submit receipts for reimbursement. Did that. United now states they will not reimburse. Currently out 2 grand.

The flight was delayed by 4 hours !!!!! It was very uncomfortable , and they told us only one our before departure

This flight is frequently delayed. The connections seemingly are more frequently delayed. I’ve missed connections as a result twice on the same route to charlotte then Charleston. Final destination arrival has been the next day, twice in a row. No pilots, no crew. Too many excuses. Unfortunately, my days with American are over.

Entertainment was okay not because anything was wrong but it is a short flight so having no wifi is annoying but understandable. Crew was outstanding as usual

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.

Flight was fine. It took an unusually long time to have baggage delivered to the carousel in ORD.

Average - flew with Jet Blue internal and it was far more comfortable and better food and entertainment. Notable difference

The flight got canceled due to mechanical issues, and he to be rebooked and missed my appointments for that day

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

The only problem experienced was a ground stop in Chicago due to weather. But the crew handled everything professionally. They prioritized rebooking those passengers who had connecting flights and then deplaning the other passengers. When the hold was lifted, they efficiently re-boarded all the passengers so that we could depart before our departure limit expired.

Our second leg to Jackson WY was unable to land due to weather. We were flown back to Dallas after stopping in SLC. We were given hotel rooms and vouchers. We were told that we would be back on the same plane in the morning. Instead we were given a different flight with different seats. Not a good experience. No one knew what was going on.

Turn on the heat. Flight was way too cold from Arizona to Chicago.

The seat are terrible. Don’t even think of sleeping on a Spirit flight. The kids that run the plane aka flight attendants are pretty rude and straight forward. They get the job done but without class.

I had a death in my family and booked my flight on Spirit. My flight was cancelled the morning of my flight, no explanation, no help to rebook, nobody to talk to. The next available flight was 2days later !!!! Terrible airline, will NEVER fly with them again!

They took a horrible route with a lot of turbulence and I eneded up getting sick. Even if the flight takes longer. Don't put people life at risk just to get to the airport on time.

I felt scam to have to pay $50 additional for my carry on luggage which was free for my other airline.

Every thing was fine ,low price,easy on time ,clean, good staff, really no issues

Had to board plan 2x due to lack of security check after 1st boarding

Miserable. The crew was rude, the flight was delayed 5 hours for mechanical reasons and then “weather” even though other planes were leaving.

They kept Changing the flight times. It was delayed several times and at one point it was supposed to depart at 3.40am! At which point we ended up staying overnight and booked long a separate United flight for early morning departure. The spirit flight then got moved up and left at 1.30 in the morning when it was supposed to leave at 9.40pm the night before.

Flight was delayed...not horribly late. Just before push back engine shut down for a quick replacement item that took about five minutes. After that, everything was smooth and the pilot was able to make up time in the air so that our arrival time was not too far off the original anticipated arrival time.

Only inflight purchases for food and water. Nothing comes with ticket price. Have to purchase bags, food...

There were 3 leg for the trip and each leg was delayed by 90 minutes or more. The boarding process takes forever with people waiting on the jetway even though most folks do not have carry-on. The whole process is poorly managed.

They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again

The process of buying the ticket and navigating all the hidden charges that Frontier throws at you was a terrible experience. The actual airport experience and flying was fine.

The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it

Terrible. Seats are bad and the baggage policy is inconsistent

Better than I expected but I did pay for a seat and carry on bags ahead of time.

I hope to avoid flying with them in the future. First flight got cancelled then got stuck with a 13 hour layover in Denver. The process was long and frustrating to many people.

Flight was delayed on the runway for 40 minutes the crew did not even offer even water to passengers to compensate for the flight delayed. The flight was delayed due to aircraft mechanical issues. Worst customer service ever

The flight was delayed and I had to cancel because I would have missed my connection and there were no other flights for the next two days. They also lost my bag!!

My first time to fly Frontier and loved it! Boarding was super easy as we only had personal items. Crew was helpful and funny and the plane was clean. Pilot was also great at landing the plane smoothly.
