Flight attendant took my carefully folded coat and flung it across the aisle to the bin across the way. Where one of the passengers rescued it for me, because that just wasn’t right!!

the flight was delayed twice and then delayed from taking off.
This was my first trip in years with Alaska. I don’t think I’ll do it again. The planes are old and tired looking. The seats are small with zero legroom. The JFK terminal is one of the worst I’ve been in. On this flight the pilot had to abort the landing and circle the Bay before trying again. I think I’ll stick with the usual suspects …
Changed flight from San Fran to Seattle Then with a Delayed takeoff barely made my connection Waited over an hour for luggage 😜
Alaska no longer allows customers to print boarding passes at the airport. They only use mobile phones for boarding passes. Try getting on an Alaska plane with a dead phone and no boarding pass! Great customer service Alaska!
Flight was delayed twice, I was forced to check my bag, and the only offered water or apple juice on the flight
Appreciate efficiency and early arrivals. Missed video on such a long flight (DCA to SFO).
I paid $49 to select my seat---6A a window seat just behind first class. When I started to get on the plane I was told that my seat had been given to someone else and I now had a middle seat. They finally gave me an aisle seat. When I told them I wanted my $49 back, I was told I would need to call alaska and fight with them to get my money back. And when i was on the flight people going by kept hitting me with their bags. I have tried calling alaska twice to talk about a refund but never got thru to the right person!
All 4 members of my family found the seats terribly uncomfortable. 2 of us suffered from back issues the next few days.
Delays, delays, delays.... (and) Told no room for carry on after boarding B Group and told to drop off our carry on at door to be checked in instead. There was plenty of room left in the overheads above our seats right up to the end of boarding!!!!
This had nothing to do with Delta… The flights were on time and flawless. The service was excellent. We purchased seats in (aisle/middle) comfort plus since this was a cross country flight. Unfortunately, the woman seated at the window was 300+ pounds and, as might be expected, covered up about a third of the middle seat also. there was absolutely nothing that Delta could have done about that… I just don’t know what the answer should be. If you purchase a seat, you should should be able to use the entire seat and not just the portion that someone else is not sitting/oozing in. Disappointing…there should be something that could be done….I'm just not sure what solution could be.
Seats are much much more comfortable than United, which is what I usually fly
If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.
Only one side of the heafphone jack work. Crew was friendly and helpful.
Great. Flight departed early and arrived early. Deplaning and baggage claim ww were quick.
They separated our seats and moved us to the back of the plane. Hundreds of dollars and thousands of miles used and this was my platinum member experience.
AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.
Got on the plane and then needed to deboard the plane because they didn’t have any pilots?
The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.
Rough day of travel all the way around. Wrong info given to us multiple times and mistakes in their booking making our trip 10 hours longer than planned. I’m bummed because I fly Delta all the time and love them. Mistakes happen. Just bummed that this was a rare trip our whole family was traveling together.
A bit rush for transit. Food and entertainment are not available
The gate was too far away for the connecting flight
Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)
The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me
For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water
Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.
Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.
Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗
We arrived early and finally made it to our gate almost an hour after.
We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again
I have long legs, my foot was out in the aisle and when a flight attendant came walking by and I didn't notice, instead of saying "excuse me" or anything like that, she kicked my foot. Extremely rude
Excellent! The gate agents were kind enough to rebook me on an earlier flight saving me from a 6 hour layover. Even my luggage made it despite the fact that the connection was technically too narrow. The flight itself was very comfortable, roomy, and clean. Plenty of space for my carryon items with plugs to charge my phone. After a long international flight of 14 hours, this was an excellent way to end my travels!
Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.
Extraordinary service in business class, and very good breakfast and snacks. A really lovely flight.
This flight didn’t happen because AA agents didn’t let us board the flight
Most of the delay was due to weather which is not what was at issue here. One delay was due to a missing flashlight and in the end the flashlight was actually found on the plane. The entertainment system is very limited. Live TV options offer only a few channels that are not very appealing. Boarding and deplaning are always difficult. It just takes too much time to get on and off the plane. On the plus side, I missed my connecting flight, but was easily able to book a later flight from the app while enroute.
We boarded after several delays due to mechanical failure and a gate change. The seat cushion in the exit row was very compressed and offered no cushion, making the four-hour journey reasonably uncomfortable. The WiFi worked for a few people, but for most, it did not, and you cannot get entertainment unless you can connect—American Airlines flights do not have seatback screens, and you must use your mobile phone.
You were more on time than United. I'm so over united delays.
The meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.
I chatted with the captain before the flight, and similarly during the welcome announcement, he warned of a turbulent flight that may impact the in-flight service. However, once at altitude, he announced that the weather changed and he immediately turned off the seatbelt sign. But it appeared the cabin crew had already decided to take off this flight. They remained seated and then just chatted in the galley. The flight was fully catered, but only first class received service.
The reps working at the airport counter were dumber than a second coat of paint.
My costume jewelry was stolen out of my bag. Got to airport and my bag weighed 45 pounds- 5 pounds over cost me $100 Long lines in tier one. No entertainment No WiFi no free drinks or snacks
Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.
The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.
The seats were awful, hard plastic covered in sheet vinyl. The airline tries to scam you into paying extra to get seat together when the flight wasn’t full. They were going to separate a family with young children but my wife who had a row to herself gave up her seat so the young mom could be with her young boys. I’m never giving this airline my money again.
It was a short flight so no food or entertainment….
Everything went as planned. Crew was great. Seats were still not that comfortable.
No frills for sure. No gate announcements about flight delay, not even water to drink on the flight.
The plane was clean, the crew was friendly and helpful. It’s a low cost airline so there was no food, drinks or in flight entertainment but we didn’t expect any of these things. In the room for improvement department, they should install USB ports in seats to charge mobile devices.
I was surprised that all baggage, including carry on, were charged. Each additional bag went up in cost. Really disappointed in the additional costs.
