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
Logan airport construction meant that boarding was chaotic crowded and delayed
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.
Don't waste your money or points on first class. Delta first class is a joke. The seats were rickety, the food was awful, and nothing worked, wifi, my light, the power plug - and it was dirty - the fold out table was gross. For 2-3 hours, tough it out in Economy.
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.
Flight was changed from departing from Boston to departing from Detroit.
AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.
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 ;)
headphone jack didnt work for the first flight and not much variety
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 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
Excellent from start to finish. All staff members were amazing!
Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.
Cancelled flight with no specific instructions to get a boarding pass for another flight. The whole flight of people were in line for an hour because there was only 1 person to help at the desk. This was unusual for JetBlue.
It was too hot in the cabin. The AC did not help.
Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.
Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking
It took 1-1/2 hours to get our luggage after we landed. That to me is unacceptable
The flight was delayed for 4 hours. Once onboard the crew was wonderful.
Overall was excellent. Will definitely us JetBlue in the future.
I rate it is good we had a 4-hour travel delay at one point but JetBlue gave out food vouchers and travel points credits for another flight so they try to make up for it
One bottle of water and a package of cookies for comfort plus. We had to literally beg a flight attendant for an extra bottle of water later in the flight due to feeling dehydrated.
Everything was fine. Flight boarded and departed on time. Seating was spacious enough for my carryon to fit under the seat in front of me. No complaints at all. Flight even arrived early.
Flight boarded from Gate 39 at OGG, the farthest gate in the terminal. There were no Hawaiian themed amenities for the flight. The first class service was mediocre at best; I received not special welcome or recognition as an executive platinum member of American Advantage program. The flight attendants were more concerned with their cell phones than saying "thank you" to the passengers as we disembarked. Fortunately, the flight arrived at LAX a few minutes early.
Bigger seats. Board back to front! Disembark front to back!
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
Plane was pretty clean, staff was friendly and helpful, flight left about on time arrived early. Took a long time to board and get off the plane - carry on items didn't have enough room so people had to move all around to find places.
The service and food needs to improve to catch up with other international flights
Would have been good to have a meal since it was a 5.5 hour flight
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.
