First time flying with any airline that has decent seating. Great experience crew was friendly and the pilot was as well.
First time flying with any airline that has decent seating. Great experience crew was friendly and the pilot was as well.
Pretty disappointing as we did leave Seattle two hours late.
1.5 hour delay boarding plus 1+ hour sitting in plane waiting for ground crew to load luggage and freight, made for 3:00AM arrival in Seattle.
The second leg of my trip left without me despite being my inbound transfer only a few minutes late. My friends told the gate agent and they closed the doors and left early anyway. Then they tried to rebook me on a flight SIX hours later which only changed when I got a supervisor to make it 4 hours later. The gate agent was nasty, unhelpful, and walked away from me.
Worst part is being squashed in a seat ( I am not fat) and unable To get comfortable
Took forever to get on board. Flights was one hour late.
They always change the schedule. My original flight got canceled. They put me up in the air flight. I had to stay seven hours in Seattle. That is bad.
I had a great travel experience with Alaska. The agents and cabin crew were all so pleasant and helpful. The plane was clean and comfortable. The connecting flights went smoothly even with some minor delays. All in all, it was nice not to be upset with the journey. I say that because over the last few years all my travel has been on Delta and American, and always involved cranky employees and flight issues. I wish Alaska flew everywhere I need to go. Will definitely fly Alaska every time I have a choice. Thanks for helping me look forward to traveling again.
Disappointed that there were no TV screens to watch a movie on the six hour flight. Disappointed that the plane did not have the right adapter to connect my phone and my iPad and charge them.
Ted. F/A in fist class did a great job! Very nice
The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.
Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!
Seats are much much more comfortable than United, which is what I usually fly
Flight left early and arrived early. the whole trip was excellent.
Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.
Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.
Delta was great the entertainment was outdated. Screen was very small and didn’t work.
The seats are uncomfortable, feels like a small seat pad on plywood.
My husband is very tall and we generally fly Delta Comfort. We used our companion benefit, and our seats were coach and extremely uncomfortable........ horrid even
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.
Not so good. The takeoff was aborted after reaching 100 knots due to a problem with the front tires. I do commend the pilot for a quick decision and preventing a potential disaster. We returned to the gate to put fresh tires on the front. Our flight was delayed for over 3 hours. The rest of the flight was okay. We were reimbursed by Hawaiian Airlines for only $50. Not too generous
Great plane, seats, and crew. Super smooth experience and delicious coffee
Liked the staff ! Seats a little uncomfortable for a 9 hour flight. Wife ‘s monitor at her seat didn’t work. Food was disappointing. Snacks were good . Choices of movies and music could have been better.
Arrived at the gate with no seats assigned. Was told by gate agent the flight was full and we would not be on it. I asked the gate agent how could I be sold tickets when the flight was full. She replied, “Thats just how they do it.” I was able to get seats once I arrived at the gate. The flight itself was great. I’ll never purchase tickets without seat assignments from kayak or anyone again. Shame on kayak or Hawaiian airlines or all of you.
The pre-flight check in process was bad. The app didn't allow check-in online and forced me to check in at the airport. Alaska didn't have self-service kiosks for check in (only bag tagging stations), so I had to wait in line with people who were checking bags just to get my boarding pass.
Hawaiin airlines never let me know the alaska airlines confirmation number. it took chat and call with customer service to get that.
Flight delays, another inconvenienced passenger, and crew serving food and drinks with hair not tied (really very messy - made me apprehensive taking any uncovered food or drinks)
A cold sandwich would be much better than the warm gummy croissant.
I think you should still be able to pick a seat at check in no matter the price tier. But the plane was decent. Seats were a little narrow so I imagine larger folks would have some discomfort but I was fine and the crew was great.
Crew was excellent......in flight medical emergency handled very professionally.....
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
Smooth boarding and friendly crew. Unfortunately as soon as we boarded the unit that provides air circulation failed. The pilot informed us and requested maintenance technicians to check it out. The plane became uncomfortably warm without any fresh air coming in. Plus the repair delayed our departure. I am glad the maintenance crew were able to fix the problem. I also was without use of my tv monitor for the first 1/3rd of the trip.
Communication with the customer and stay is important. Staff off with a minor inconvenience but it worked out of course. Also this was a very old Mint Class plane. They snuck this one in on us. The updated aircraft are much better.
There were five broken seats on the plane. The crew was very rude in telling people they had to get off the plane and get a flight the next day. No call for volunteers, but telling people they had to get off. One woman was flying with her elderly mother and daughter and was told she had to leave or all three had to leave. Fortunately, a volunteer offered to stay. The situation was handled poorly.
The flight to Tokyo AA61 took off about two hours late, but then had to turn back. By that time the crew had to be replaced. Then they kept promising to take off in an hour, then in 3, then switch to the next day.
Any sort of gluten free snack option would be nice
They lost my luggage and it didn’t get delivered until the next day.
Would have thought that they would gas up plane before everyone got on board
3 hours late. Not even water offered on a 2.25 hour flight.
I had a carry on and a personal bag. I put my personal item under my seat and on way to the seat I put my bag up. I usually close my eyes and rest as I was on call for last 36 hours. I heard very loud announcements that someone needs to identify their bag. Pretty sure it was not mine until the hostess pointed out my jacket details attached to the bag. I asked why she got my bag out. I got berated and did not want to create a scene. But this person needs to be talked to.
Terrible. The flight was delayed two hours due to weather. Then when we got on the plane, the first pilot ended up timing out and we had to wait for a second pilot. Second pile came on board and we tax it out. Had to return back to the gate because of an unruly passenger. Then the copilot timed out. Had to wait for new copilot. Also had to wait for maintenance to check for fuel. Then found out the second pilot timed out and we had to wait for a third pilot. Was ready to go and then needed maintenance again for another issue. In the end, it was 2 o’clock in the morning when they announced that the flight couldn’t go because the third pilot and the second copilot had timed out.
To start, I’d like to say that every American Airline personnel I interacted with on the ground, especially flight crew, was very friendly and did their best to help me out. Despite this, however, my experience with the airline was an entire mess. The 7:19 PM flight was heavily delayed due to weather, and pushed to 10:30 AM the next morning. Because of this, I had to spend the night inside of the airport. At some point later in the night, I got an email saying that the flight had been canceled. I called the support number, and the representative on the other line told me that the flight was still on and that I didn’t need to rebook. The next morning, no one came to the gate to open the door for the crew until almost 11 AM. By this time the flight crew had been waiting for over an hour, and they had called management to get someone to open the door for them multiple times. Around 11:30, the gate screen had changed to a different flight. I ended up buying a last minute ticket with Southwest airline just to get to Chicago, because the next flight with American wasn’t until 7:19 pm that day. Now, earlier that morning my suitcase had been sent ahead of me to ORD. I went to baggage claim to ask them if I could have my suitcase forwarded to where I was staying. The representative at SDF baggage claim said they could and put the claim in for me. As I was going back through TSA, I got an email that the airline had found my suitcase, but the next step was to send it BACK to SDF. I called the airline support number again, and I made it clear that my suitcase needed to stay in Chicago and to not come back to SDF. The representative told me that they would hold my suitcase at ORD and that it wasn’t going to be forwarded anywhere. Once I got there, I found that they had loaded my suitcase onto a plane to send it back to SDF. Thankfully, I had gotten to the baggage claim counter in time for them to put in a request to bring my suitcase back up. My refund with the airline is processing already, but because of this entire experience and miscommunication at every turn of the way, I will not book with American Airlines in the future.
American Airlines initially postponed the flight. Then they cancelled it an rescheduled us on a flight that would take over 24 hours with multiple stops. They then changed this flight to a reasonable alternative the next day which they later cancelled and replaced with a flight that would take off with an additional 16 hour delay. They blamed weather but I noticed (at 4am) that Delta had direct flights from Charlotte to Detroit. I went on line. Booked it and was in Detroit buy 9am. The interesting thing is they did a similar thing to a family member just 2 days earlier. I don't think I will fly American unless I have to.
