Wonderful as always! Pleasant staff, smooth ride, and timely departure.

Everything ran like it should. Staff was professional. Looking forward to flying with them again.

Boarding much smoother than previous United flights! The flight attendant helped monitor putting bags in overhead bins. On united no help resulted in bins in first class being filled before I boarded for first class. I had to search further down into economy. Then got stuck unable to return to my seat. People were putting backpacks that needed to go under seats in bins. It was a mess. This flight was a refreshing improvement. United also had so many categories of preboarding that first class could not board early. The pilot talked to us directly instead of using the intercom before flight.

Liked the attention and speed when getting wheelchair..........Was assured by phone that my needs would be taken care of and they were with my name.

The planes were in very nice condition. Comfortable enough leg room. I had a very quick connection on my return home I made it just fine and so did my luggage!!

Everything was fine. The snacks are a little on the tiny side.

Most of it was good. The flights were on time. The staff were helpful and friendly. I had a short time connecting flights and they let me deplane first and I made the connection. On the outbound from DTW to SEA I was seated in the middle of two very large people. I am petite and even with my arms crossed they were both hanging over into my seat touching me. The meal had way too much pepper and spice, my lips were burning. Other than those two issues, I was pleased with the service and the trip and will use Alaska Air again.

The seats were spacious and comfortable. Even in basic economy. However, the flight boarded 30 minutes late.

Alaska used to be a top notch airline. With it's growth it is now in line with the big airlines. Not bad, not great.

Wheelchair assistant was on the spot, and very helpful. Gate agent was kind, and made sure I boarded the plane without having to try to hurry with my painful hip. My seat was so comfortable, 20A. I am tall, 5'9 and I need to stretch out my legs due to chronic nerve pain in my back that runs down my right leg, in addition to the bursitis in my right hip. Alaska air has the best economy seating in the market. So much room for legs, elbows, etc. When I arrived in SEA, the next Wheelchair was waiting to take me to the next gate. Great communication.

The whole experience was excellent. As it most often is with Delta

Cabin was not pressurized properly. Several passengers had respiratory difficulties.

I was happy that I was able to get a last minute flight but unfortunately my seat was a middle seat. Even with Delta Comfort I wasn't comfortable

There’s not much to say about a one hour flight. This is a connection from LA to RNO that I missed the previous night due to a mechanical check delay on my originating flight from JFK to LAX. The short flight itself was fine. Instructions from the pilot and crew were per usual. The coffee was barely lukewarm, which possibly was purposeful so we would down it quickly. Bags were already on carousel upon reaching baggage claim, which was excellent.

Flight was warm for first few hours and quite rough

Seat was extremely hard which made even a short 1 hour 20 minute flight fairly uncomfortable.

Everything was good except wifi and a leaking drink chiller. The floor was all wet and my bag was soaked. Did not notice until debarking. Have not heard back from Delta. Even though this was leg one of an international flight in first class, they denied access to their Sky Club - very disappointing!

The staff was fine. The plane was extremely tight, and I paid for the wifi and it did not work at all. I was actually going to ask for a refund.

two hour delay and the Delta representative on the PA system was unable to understand

An awesome flight crew. FC seat cushion just doesn’t cut it for a 3+ hour flight.

It’s always a great time flying with united airlines.

Good flight. Efficient boarding and competent flight crew. No problems until we arrived at our destination gate. We were early so there was an aircraft at the gate that had to move before we could pull in. Then, due to the type of aircraft we flew, the cabin door could not be opened until some luggage from the cargo bay was offloaded to preserve center of gravity characteristics. So, that further delayed deplaning. Despite being 20 minutes early on landing, we ended up being 5 to 10 minutes late after all the delays.

Everything went well except the turbulence what no one have a control of but pilot and crew handled very good!

There was no WiFi available, there were mechanical problems with the plane and we landed at C 124, then the gate was switched to A 26, then all the way back to C126! For a 75 yo woman traveling alone, this was a difficult journey, indeed!

This trip did not start off well. The inbound flight was delayed about 20 minutes. Then, after initial onboarding, the passengers had to deplane due to a mechanical problem. That took about 30 minutes to fix and be cleared. Then, reboarding was chaotic. It took a long time to sort passengers and two passengers on standby were ticketed but there was no seat. So, they had to deplane. One of the flight crew was trying to help passengers figure out a place to put their carry-on bags and that took more time. In the end, our scheduled 10:30 am departure did not actually take off until about 12:05 pm CST. The flight itself was long but we got to Houston. Some passengers missed their connecting flights and had to rebook. Not the best of flights I've had.

Staff were good. My seat was in need of repair, but for a short flight was not problematic. Usual basic snack and drink setup that you'll find on any US carrier. Over, a decent, basic flight.

Complimentary light meal would be appreciated. But great flight crew service on all legs

Flight delayed for more than 16 hrs and no effort was spent to provide an alternate

We got delayed three hours and nobody thought to have the bathroom fixed while we were sitting waiting to board? took a full hour to have maintenance come and check it off. Had to shut the bathroom down twice so that the pilots could go to the bathroom. Everyone missed their connections.

Flight left on time and we arrived 25 minutes early! There was a gate available when we arrived so early on a busy Sunday afternoon! Flight attendants came around twice with the drinks cart.

I very rarely fly American and my experience today reenforces that is the correct decision. While the staff were all very courteous, our flight was first thing in the morning so there was no reason to be delayed, yet appropriate maintenance checks weren’t completed prior to our flight so we were delayed multiple times. Not a great showing, American Airlines.

Boarding is always an ordeal. Less dogs on flights. I am highly allergic to dogs and cats. Why are there so many animals these days?

I was on a small regional flight from Detroit to Philadelphia. When we landed the outside cruise needed to turn something off with the engine, which took quite a long time. Then, when they allowed us to get off the plane it was outside. They took their time, unloading all the luggage and waited till they unloaded all the luggage before they brought it over to us. It was 9 o’clock at night freezing cold out, and there was no proactive hustle to try to get people their luggage. It was really one of the worst experiences I think I’ve ever had with American until a manager came over. I don’t think they were going to even consider pulling the luggage over to the people that had been waiting outside for at least 10 minutes in the freezing cold.

Awful. Original flight was delayed 5 hours. Had to to take a connecting flight instead of direct. Had a 4 hour layover. I missed all of my morning meetings getting in 5 hours later than I was supposed to and had to change to take a later flight the next day to get them back in which cia time another $150.

I was trying to take 2 one and a half hour one way trips and I experienced almost 20 delays over the course of those two trips. Only a few of them were due to weather the rest was disorganization

The attendants were kind and helpful. A sugar-free drink would have been very welcome.

The entertainment options were at best, fair. It was exactly the same as my outbound flight. It would have been more entertaining if there were some series from Apple TV, HBO, Showtime or other carriers for me to catch up with.

The seat cushions were very worn so they were extremely uncomfortable.

Crew were all friendly and helpful. It was a short flight so just a beverage service with a cookie. After we were boarded the plane took about 45 minutes to leave the gate but it was New Year’s Eve so not shocking there was some delay. Overall good experience and very grateful.

the trip to madrid was uncomfortable with my legs touching the seat in front of me
