Original flight was delayed, then cancelled and the gate staff did not expedite rebooking. Also, no instructions were given that a ticket number was needed before being called to facilitate rebooking. This could have been much more organized.

Be on time? When not on time a circling for over an hour offer more than 1 bag of chips to the passengers? It was a 7 hour flight by the time we got done.

Five hour delays every hour, I wish it were all at once

Flight delayed four separate times. I’m now one hour hours late to landing.

worst flight ever from Delta, it got delayed and kept on delaying..

Should never have had to go to Detroit from Orlando back to Tennessee!

Got rerouted from a straight flight from Orlando to Atlanta to Knoxville to a flight from Orlando to Detroit to Knoxville! Seriously!! Flight delay out of Detroit! Long day for what should have been a pretty easy travel day!

Two delays on two separate planes with parts they could not easily find and replace.

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Only beverages were offered to first class and I thought the flight attendant could have also served the Delta Comfort as well instead of sitting down and staring at her phone and walking past all of us to the back of the plane to charge her phone more. There was a complete lack of turbulence and was safe enough for flights attendant to walk around in the front of the plane, collect trash and serve a few people water and turn off the seat belt light. Also didn’t enforce people putting their seats into the upright position and allowed two passengers to remain reclined during landing. They seemed out to lunch completely. Usually my experience on Delta is much better.

Horrible! Several delays and then was cancelled! I spent over 24 hours in the airport and was unable to get a hotel or food voucher.

The entertainment they offer could use some games, and maybe they could add some cookies to the snack menu. And the automated messages are a bit repetitive. But it was comfortable temperature wise and the seats were comfortable. The crew is very polite and helpful

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

This planes staff was top tier. Everything went great and had a great flight home.

Food was great. Staff was phenomenal. Seats were a bit hard and could use a lot more entertainment options as far as movies to choose from. WiFi was good. Overall great trip.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

I was promised by United Airline (operated by ANA) that I will be seated together with my kids as I am the only adult flying with two minors. We did not get seats together in our 11 hours flight from LA to Tokyo. When asked at the gate, ANA representative said United Airline should have informed them that there is a parent flying with two minors. He said they can’t do anything in the system as the flight is full. He ask me to ask passengers next to me and the kids if they are willing to change seats. This is ridiculous! However, I went in the flight and asked other passages but no one willing to change seats. 11 hours and we were seating separately. I was very disappointed with this. It made things super inconvenient for me.

Our flight was delayed several Times due to mechanical issues. Although I understand this may happen at times, it was very inconvenient and we had to book a hotel for an overnight stay. We were traveling with my 3-yo grandson and waiting at the airport from noon until 6:30pm with no reassurance that our next rescheduled flight would depart, we had to decide what’s best for him. A day later, I found out that I may be able to demand compensation if my flight is delayed more than 4 hours. I will hav to read the fine print next time.

Flight cancelled instead of leaving Friday am now, maybe, leaving Sunday

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

Aer Lingus App never showed the gate and the board did not update until very close to the time the gate was due to close. Both planes departed late but no announcement was made which would have saved a run for the gate.

Flight delayed 45 minutes almost caused us to miss connection to transatlantic flight.

Vegetarian food options were pretty tasteless. Gob of rice with absolutely no protein, barely any vegetables, and poorly seasoned. Food was the major disappointment of an otherwise good flight experience. However, food is a differentiator on long haul flights.

We were an hour and a half late, which caused my rental car company to cancel my reservation. We had no car, had to take a taxi to our hotel, and then a taxi back to get a new car the next day. Sometimes lack of on-time performance can end up costing the passenger a lot of money, none of which is covered by the airline that operated the late flight.

Overall good experience. But seats were small and uncomfortable for the price. Good entertainment, staff friendly and attentive.

Flight was delayed no information given really . No food whatsoever on the plane . I think you should be able to put that on the app so people have a chance to buy food bring it with them . They said plane was very busy on way over but there should be enough for both flights as we pay full price for the service. No information or very slow on the app about the delays . Staff were lovely it’s not their fault so company not fare to passengers or staff .

Smooth quiet flight take off and landing both excellent. Food was mediocre. Boarding at gate was disorganized and unacceptable.

My only complaint is that during my 8-hour-long flight, the flight attendants came around with the coffee and tea cart twice instead of the alcoholic beverage cart. I would rather sleep on a plane than rush to the bathroom to take a dump. I asked the flight attendant if I could have a beer instead of coffee or tea. Unfortunately, she said the bar is closed. That tells me that she was too lazy to get me a beer on the plane. I was not happy about that.

Caring & friendly crew. Most important: got us SAFELY to our destination!

Friendly flight attendants, decent food if you can eat dairy.

Crew were professional and kind. The flight was smooth. But... The internet, which we paid 35 dollars for, did not work for most of the flight. This made providing media for our child an uncomfortable hassle.

Overall fine. Seemed like one of the older model planes? Crew was mostly very kind, though some of the female attendants were a rather abrupt during the food service.

Awfully rude American worker at door when we started boarding flight. Then, walk into a blazing hot airplane with no air conditioning until twenty minutes into the flight. Free entertainment was non existent! My husband, along with the fellow passenger in our row, and I could not get entertainment to work, no WIFI! Really?? Been flying American a long time. Was very disappointed.

Flight was delayed by 6 hours... the level of incompetence was truly astounding. I won't be flying American Airlines again. I don't care if AA is direct and there is a layover with another airline, I'll take the layover.

Leave on time. We waited on the plane for hour hours and it was hot and smelly

Two hours delay, probably one hour because they didn’t bring catering and they had to bring water in board. There a change of aircraft. But delays galore at CLT so it must be a CLT and/or AA operation issue. The 1 hr additional delays because nobody could bring 2 packs of water sooner is probably the best example of this airline operates

Flight was delayed 5 hours. Initial reason for delay was 'maintenance' - which makes sense. Then, the additional 2 hours continued to say it was maintenance - when I know EWR had a 2 hour delay. AA did not say that. Additionally, when boarding, there was only one agent at the counter for a long time - until another came to help. After boarding, we had to wait another 45 minutes due to 'no catering'. So while we waited for catering, AA continued to board additional passengers - which seemed odd - and raised questions about what really was going on. I sat in First Class. During the flight, the flight crew allowed a significant number of non-First Class passengers to use the front bathroom - which created a very crowded environment in First Class which was uncomfortable. This also delayed First Class passengers from using the bathroom. Overall, horrible experience.

The Charleston, WV airport was cute. Very good staff and small enough to feel comfortable. The plane had more leg room than bigger planes. Much more comfortable.

Another uncoordinated American experience. Always surprises me at DFW for them of all places. Have to take this flight as there are no other good time options. We knew from the start that something was wrong, but the pilot wouldn't tell us. I just watched my Kayak app grow the delay by 10 minutes as it went to 3.5 hours. They were uncoordinated with maintenance (as maintenance, when finally arriving, knew within 15 minutes the plane wasn't going. No 'sorry' or 'this is what is going on' comment. The pilot seemed unfazed / didn't care about the process we were going through.

The seats. The seat in front of me was awful and when the guy sat down, it flew back and hit my head when I was putting my backpack under the seat, It didn't make for a pleasant experience,

It was inexplicably canceled and we are stuck in LA, haven't gotten home and it has been an inconvenience having lost work (on unpaid leave for my husband).

I like everything. Blythe at DCA is the absolute best!

JetBlue worker, Blythe, was so amazing at the DCA counter. If it wasn’t for her, I’m not sure we would’ve made it through. Please thank her!

They lost my luggage and refuse to help. Terrible airline. I've never experienced worse customer service in my life. Pretty much just told me too bad that I lost all my luggage, not caring that I am stuck in Europe for 2 weeks with absolutely nothing.

You should have had Wifi to make it much enjoyable.

The flight out was delayed from 3:40pm to 5pm and again to 8pm. We boarded after 5pm, had to disembark because they could not get the Engine started, then we switched gates and got a new plane and did not board until after 8pm.

The flight was delayed after already taxiing from the gate due to a malfunction. After 3 hours we were told the flight was canceled. The next flight available was Sunday. My daughter and I stayed overnight in the airport due to this issue. I was given a $12 meal voucher. Unacceptable

Whole experience was poor. Delayed 2 hours. Lied about the delays. Was all jet blues fault and tried to blame on air traffic control. Sent out other let trips and wouldn't allow people to switch aircraft.

My bag was not loaded on my flight. it was not communicated to me until i was waiting for my bag at my destination. there was no confirmation of when my bag was arriving and no way to track it.

Nice plane, clean, wifi available and movies. All the flight attendants were courteous.
