Anything to make the customer experience better. Stop cancelling flights like people traveling have nothing better to do than have their life plans halted. People go to great lengths to get time off work, make plans at the end of their flights, make travel plans, go through the nightmare of checking in at busy stressful airports, make pick up arrangements only to have the rug pulled out from under them. Flying has become so miserable now!! The flights were delayed ONLY with American Airlines. The disorganization is sickening. After the flight being delayed multiple times, when the flight was finally broadcast that it was a go, EXCEPT, they were now waiting for flight attendants. They had plenty of time to plan this, what the heck?! Missed both connecting flights because it was so delayed. I vowed to never fly American Airlines again, did it and BOY was it a mistake!!! American Airlines ranks with United as two worst airlines.

late flight, no wifi, no entertainment, no snack. What are you coming to????

Missoula is a great airport. Desk and gate crews were very helpful and friendly

No communication with delayed and canceled flights. Completely in the dark for the whole experience.

The flight attendants were friendly. I liked that I got a mini soda can, not just a small cup. No issues with our flight departure, etc.

My wife and I had seats next to each other, but when our boarding passes were printed, British Airways had moved me away from her and refused to fix it. We tried to fix it at the boarding gate and were just told flatly "no". Never again.

Close boarding too early we’re willing to not let people on flight that could not check in. What ever happened to customer service? Three of us had to fight to get on plane shameful

On my trip from Seattle to San Jose it would’ve been nice to have the gate transfer nearby instead of at the opposite end of the airport that’s it

Personnel were helpful and caring. On my first flight I was seated near the rear of the plane. Before flight and after landing the smell of urine was strong. The nice stewardess tried to cover the smell.

Plane was supposed to leave at 5:40 left at 6:03 had to walk really fast to get to connecting flight just making the flight.

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta was fine though my flight was delayed 4 hours into LGA and my return into ORD involved a taxi of 1+ hour to the gate

It was as good as it could be. Flying is not a pleasant experience these days.

There was an unruly family behind us that made the short flight miserable!!! The cabin crew did nothing to contain it.

Flight delay was frustrating, also you cannot checkin online without delta app, web browser check-in throw errors

Got on the plane and sat there for an hour before departure.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

Cramped seating for me. Luckily it wasn’t a long flight

5 hour delay. They blamed the weather but it was the computer issues they had been dealing with for days.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

Awful. Delay after delay. And then again on the tarmac.

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

Food was not Good Nuts came very wet & not tasting Good Main course I asked for Steak they got me Chicken because they don’t have more !!!!

It cancelled and we were unable to catch our connecting international flights.

Leaving at 7 when scheduled to leave at 4:20 - you tell me. Understood there was a ground stop. Then having to "reboot" the plane because of a lighting strike, also understood. But basically the flight was a "clusterf#$%".

On boarding crew at the airport called in the boarding numbers too early meaning before the previous line was completed resulting in later numbers getting to board ahead. Also she asked those who boarded from number 3 to have the tags in their carry-on bags and leave it in the jet bridge. Most of the overhead bins were empty though. This is more work for the ground staff in addition to more inconvenience for passengers waiting to get their carry-ons from the jet bridge.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

Horrible. Flight was delayed for 4 hours first till 7pm. Then for one more hour. Then again and around 9pm we were finally boarded and waited for catering delivery for another hour. At 10pm we were not interested on food at all. Tired, sleepy we arrived after midnight. Insane.

I've never seen such poor lack of information at a gate station in 69 years. The flight from COS was to depart at 12:37pm. At boarding time, the gate agent in the microphone mumbled something completely unintelligible. I understood one word. "mechanical". Nothing else. Absolutely nothing else was reported for the next 1-1/2 hours. Past the time for departure, at 12:37pm, the gate agent simply walked away and the station was left unattended, as all of the passengers waited expectantly. The board still said that the flight was ON TIME. That was hard to believe since it was then well past 12:37pm and we all were sitting at the gate and there was absolutely no gate agent anywhere in site. I stopped an employee who was standing somewhere else and said that we can use some information. Much later, the same gate agent said that he will have information for us about 5 minutes but he "doesn't know any more than you do." Of course, five minutes came and went and he did absolutely nothing. One and a half hours after 12:37pm, he opened the door and began boarding. No explanation, no apology. Once we were boarded, the same happened on the plane. We sat. No explanation, no apology, from any flight attendants. Finally, finally, a pilot apologized and explained that there would be a delay. WELL NO KIDDING !

Our flight from Chicago to Des Moines was the problem flight due to a dismissive flight attendant. His conduct was unnecessary and unprofessional.. I will avoid using Americam Airlines again because of the situation. Very disappointing.

Mostly excellent. However, many too many gate changes. Connecting flight at ORD changed gate 6 times.

Mechanical issues and delays. I get it but bad experience. Turned my 3 hour airport experience into a 9 hours

The baggage process at the gate was terrible. Stay was not friendly at all

Flight was delayed because of mechanical. Could not get landing space which caused me to miss my connection. Messy and not organized.

We landed slightly early but then sat in holding area waiting for our gate to clear out for about an hour, so technically we arrived one hour late at the gate at ORD. The airport may be partially responsible here, but regardless of who is responsible, it was a bad experience to be so close yet unable to get off the plane.

Delays and cancellations. Mechanics weren’t on site. Replacement plane took hours to arrive although it should have arrived within 90 minutes. Flight back was cancelled. Ended up driving over 12 hours and wasting 3 days between everything.

The flight from DFW to chs was delayed with multiple gate changes.
