The boarding was horrible. You couldn’t hear the announcements at all. Probably because there is so much in the area for businesses. They need a louder PA system. Other than that it was a good Delta experience.

The boarding was horrible. You couldn’t hear the announcements at all. Probably because there is so much in the area for businesses. They need a louder PA system. Other than that it was a good Delta experience.

Everything was great. The big planes could still stand to have a bit more leg room. Crew was amazing!!

On 2 different flights the wifi was horrible and there was no drink or snack service.

The pilot was excellent - he flew us around a storm and even though predicted it would be a bumpy ride - was able to avoid all turbulence and land us safely with only a 15 min delay. Kudos!

Great flight crew, easy boarding, delicious snacks and spacious seats. Love flying delta - worth the price.

There was no FREE wi-fi nor entertainment screens at all.

Delay at gate caused a flight change for our connection, hotel stay, and lots of standing and waiting in lines which hurt my feet and was unpleasant as people were grumpy and yelling. Delta worker Nestor Espinosa was very helpful! Others were apathetic (tired I’m sure!) but weren’t clear with instructions and didn’t give both of me and my travel partner the same food voucher etc.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

From boarding to the next 45 min to 1 hour, it felt like a sauna, felt like vents were working but no AC on.

TERRIBLE, THEY ARE THE MOST DISORGANIZE AIRLINE A HAVE KNOWN

We enjoyed that we boarded and took off on time. We didn’t like that our connection flight was a twenty minute walk through the airport with only one hour in between flights.

No lounge access with “United First” ticket. False alarm about late flight, jeopardizing connection. Wrong meal. Loose power socket would not hold plug, could not charge device. In-flight access to text messaging did not work. Toilet seat on plane would not stay up.

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

Boarding was terrible. My wife uses a wheel chair and she was in an incredibly hot closed metal cargo box for close to 20 minutes before getting on board

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

It was okay, no wifi or entertainment real disappointment. Staff onboard not very friendly.

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

It started with multiple delays, cancellations, re booking, 5 hour lay over and finally on a plane from Chicago to Pittsburgh. Gates, times, etc were changed multiply times. Once on the plane, staff was fine, but built in tv did not work and could not even turn it off. Light at eye level the entire trip, so sleeping was near impossible. No snacks or drinks given.

Both flights yesterday, experienced hard landings. Harder than I’ve ever felt before. Im hopeful there was weather involved and not pilot error. Other than the landing, the flight was quite good~

The flight was 90 minutes long and the stewardesses were extremely slow. I was in row 16 and they did not serve us drinks until we were descending for landing in a 90 minute flight. Unacceptably slow and at least 10 rows (20 to 31) did not receive any drinks or snacks for the entire duration of the flight because of the slowness of the stewardesses. There is no rationale to delay beverage service to brew coffee for a flight at six p m.

Flight delayed, boarding time kept changing, not good. Nee firm information given each time.

Couldn’t use car seat due to lack of window seats available was disappointing

Best price with timings that suited us. The flight was punctual.

After my luggage was grabbed by another passenger, by accident, I chose to speak with the American Airlines staff within the airport. Not only was the customer support staff uninformed but also very argumentative, making this situation harder to deal with. I was only able to finally retrieve my luggage thanks to the passenger who took it contacting me due to the tags on the luggage. All of this was happening during another 2 hour delay and 3 gate changes. Horrible airline with disgusting, on the ground, customer support staff.

The experience with American Airlines was terrible from beginning to end. Flight 1210 from Cancun to Charlotte was delayed three times. AA customer service at the CUN airport could not provide information on why or how to accommodate me if I missed my connecting flight at CLT due to the delays. Upon arrival to CLT, de-boarding the plane was a horrible experience. You all should have allowed passengers with departing connecting flights within the hour, to get off the plane first! It caused so many passengers to lose valuable time waiting to get off the plane, and then the long lines in customs! American Airlines knew passengers had to make connecting flights and still chose not to hold the plane? I missed Flight 2758 from CLT to DCA for that reason. Waiting three more hours for the next - Flight 1269 from CLT to DCA. Once again another delay at the last possible minute before boarding due to the plane going out of service/maintenance. Once the new plane boarded, we sat on the tarmac for 40min. I did not arrive to DCA until 12:33am. I spent over 12hours at the airport and I plan to never fly American Airlines again.

Having issues traveling with AA for last two years, became a huge gamble

The flight from Guadalajara to Dallas had mechanical issues, and was delayed every half hour for 4 hours until we were told to rebook. As it was during the busy holiday break, most flights were fully booked and travel that day was unavailable. The only saving grace for American Airlines was their ticketing staff that maintained their composure and did their best to accommodate all the disappointed and frustrated passengers.

It was only a 50-minute flight from CLT to SAV. I could not get wifi in CRJ 900 plane,
