Lester and the rest of the crew were such a joy. Also, I want to thank the pilots for getting us there on time, and safely. My first amd only choice will always be Alaska Airlines.

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

Not delay for a few passengers. That was uncalled for. If idiots can't make the flight on time thats their fault. Why should I be punished for them? No more holding the plane for one or two people

The agent changed my seat and upgraded me free. The flights are ALWAYS delayed. We sat there almost an hour while the plane was held for 4 passengers. I was then unable to make my connecting flight. This is why I dont fly alaska unless there are no more flights with delta

Santa Rosa Airport is the best! Glad to have experienced it.

good, no complaints but nothing to rave about. It was fine

I love Alaska! We arrived on the later side without seat assignments only to find the had oversold the flight by 1. The attendants worked extra hard to find a way for our party of 7 to stay together and we made it on the flight! Loved the free WiFi also!

I paid for the WiFi and it didn’t work during the whole flight

Impressed that Alaska Air(for our domestic flight) transferred our checked bags to EVA (for our international flights) so that we didn't have to handle them, & we just picked them up at our final destination.

The flight was on time and got in early which allowed us to get to our next flight.

The WiFi and crew on the plane were good, however, the boarding experience was awful. I paid for the Choice Preferred and was boarded in group 5 so all overhead storage was full. They found room for our luggage, but further back making getting off the plane a nightmare. Also, we were in row 6 and the seats were extremely uncomfortable. Both my daughter and I had no leg room and couldn’t wait to get off the plane.

The charges were ridiculous for an hour flight and the turbulence was very scary.

Still need to work out the kinks on the new assigned seating boarding process. Otherwise, a very good flight.

WiFi did not work. Boarding with the new seating assignments took too long. The temperature in the terminal was obnoxious. +/- 80°

The seats are now more narrow. I paid for front row the seats in the front are even more narrow than before.

Only downside was the legroom and seat width, which is always a problem unless I spend more for a premium seat.

My flight from Denver to Minneapolis was excellent. My flight from Minneapolis to Denver was one of the worst I flights I have ever experienced. I had a window seat, the gentleman in the middle seat was morbidly obese and SW should have made him purchase two seats. His elbow dug into my arm most of the way even after I asked to please be careful. I was literally squashed between the him and the window with no wiggle room. The plane was full so it was not possible to ask for a different seat. I realize I should have complained to the flight attendant but I didn't feel anything could be done to rectify the situation. I fly SW often, I will continue to do so as this was my first negative experience.

I was assigned seat 7E, yet my boarding was Group 5, which caused me to have to put my luggage in the back of the plance above `19 or 20 aisle, as passengers who had boarded earlier took the overhead bins in the front. SW needs to monitor bin space and ensure that bin space above the seat are aligned to those sitting near their seats. Also the seating assignments needs to align with group number. Maybe board those last first and so on? Having said the ALL the passengers on the plane were gracious enough to allow me and other passengers in this dilema to retrieve our luggage and helped us along the way. I always love the flight staff, as always their fantastic and I can't rave about them enough!

I appreciate the staff who allowed me to board though I arrived a little late! Regarding the assigned seating, I had booked my flight before this change and wasn't aware of the change at the time, and so I didn't select a seat at booking as I didn't realize it was relevant. Better communication about the change would have been helpful for preparing.

Flight attendants very hospitable and friendly. Pilot flew a smooth take off and landing.

Everything I mentioned earlier - the airbus was more comfortable indeed and the experience was further enhanced.

Delta continues to set the benchmark for traveler-friendly service with minimal disruption and clear communication within the mainland US (coast to coast). I am consistently pleased to be a Delta customer, and this experience once again met my expectations. There was a brief delay departing from MIA due to a technical issue that required the aircraft to return to the gate. However, the situation was handled professionally and transparently. Fortunately, my planned layover allowed ample buffer time, so the adjustment caused no stress. Overall, another smooth and reassuring experience.

Good experience and the flight landed early. There was no food I had or entertainment.

Flight was delayed and no reasons provided. After the passengers were boarded, the crew made announcement that the captain has jot arrived and he would take another 15 mins. All passengers patiently sat until the captain came and started. Terrible experience!

Flight was delayed. No information on why it was delayed. After we boarded the flight, , the crew made announcement that the captain hs not arrived and he will take 15 mins more to arrive. Passengers were just sitting patiently for the captain to arrive and start, Terrible experience.

Totally worth the miles to upgrade to Delta Comfort. Plenty of legroom.

This was my first time flying Delta ever and I had a great experience!

Smallest leg room I've ever had on a plane.

They took all carry-on luggage from Groups 6 -9 - I was group 5 and waiting in line to board - they made me check my luggage too. That then went to baggage claim and delayed departure from the airport. There was overhead room in my seating area - Delta over reacted. Also, had a gentleman next to me that took up 1/2 my seat.

Excellent!!! Aeromexico is a great airline. What was not that good is the service provided by Kayak. It is never clear and not easy to manage.

Entertainment kept turning itself off. Gave up on watching a movie.

Both the WIFI and entertainment did not work for 2.5h

The crew made our experience extremely bad. They were rude and didn’t have anything for kids.

Very old flight - time to retire it for newer airplanes

2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

Very disappointing given gate agent behavior. Filed a formal complaint with United.

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

Crew was great (professional, attentive, prompt). Snacks for 4 hrs flight is deplorable.

Flight delayed. WiFi connectivity very poor if not existant. Last minute arrival forced me to run to catch my connection.

Both of my flights arrived early and check in process was smooth

The smell from the bathroom kept wafting through the cabin. It made people sick.

The flight was really crowded. Flight attendants were just ok.

Boarding delayed 20 minutes for no reason, no wifi, in flight entertainment, or snacks / waters?

Didn't get a seat assignment until the last minute even though i picked a seat.

American has been able to implement an algorithm that makes it possible for nearly every one of my evening flights to be late. Congratulations!

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.

The flight was fine, once we got underway. It was more than hour delayed

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

Waited for oxygen tanks for 30 minutes after boarding was complete.

The seats are too uncomfortable for anyone over 5ft 8in. I'm 5'10" with a back and hip issue and I was in pai for the full duration of the flight.
