No service flight that took 5 hrs and a stop at an unscheduled airport. Crew and pilots did their jobs

Clean planes and not take my comfort class seat away.

Weather caused a long delay, but the efficiency and updates from the pilot were helpful. We were able to make our connection fortunately.

Planes were clean, no water or snacks on either flight.

Free & relatively fast Wi-Fi. Would've liked a wider drink selection.

I continue to be satisfied with Delta’s excellent service out of LGA. The digit id works well and gets me through security in no time. Whenever possible, I choose Delta.

Was revoked with Jet Blue due to delay from Kenya Air

Enjoyed it very much. Especially liked the free WiFi that Delta offers.

Smooth flight. Left on time, and got in 15 minutes early. Onboard video was great

For some reason, TSA Atlanta didn’t have my bag on the flight on time and they don’t have to provide Delta a reason for that.

These airplanes should be illegal. The seats are two tight, it is a safety issue. Wheelchair support was ridiculously slow. We almost missed our flight.

It was a short flight so I was expecting too much

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

Flight was delayed but more than 90 minutes. This caused me to miss my available windows for pick-up by a friend. I had to pay $125 for an uber back home from the airport which was an added expense that I had not budgeted for my trip. Staff was friendly.

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

6 1/2 hours from Tampa to SFO on a Boeing 737. Cramped. No Service. No real food. One pass for coffee at the beginning and a second pass THREE hours later. And check-in in Tampa was nasty even by United standards. And I am at almost TWO million miles on United. It's a non-stop. But terrible service.

MY FAMILY'S LUGGAGE WAS LOST FROM ROME TO BARI. I WAS THE ONLY ONE THAT RECEIVED MY LUGGAGE FROM ROME TO BARI. AFTER DEPLANING IN BARI, WE WASTED A LOT OF TIME AT BAG CLAIMS LOST AND FOUND REPORTING THE CLAIM AND PLEADING FOR THE BAGS TO BE DELIVERED THE NEXT DAY. WE WERE TOLD THAT IT TAKES 3 DAYS MINIMUM TO DELIVER. MY DAUGHTER AND MY GIRLFRIEND NEEDED THEIR PERSONAL THINGS AND WE WERE STAYING 3 HOURS AWAY FROM THE BARI AIRPORT. WE HAD TO DRIVE 3 HOURS TO THE AIRPORT TO COLLECT OUR LOST LUGGAGE THE NEXT DAY. WE ARE NOT HAPPY WITH THE EXPERIENCE

We had a delay, but thankfully I made it to my connection. Overall it went smooth

The flight had a delay but I made it to my connection. Flight was smooth overall

Cancelled flight. Still waiting to get home for grand daughter’s graduation .

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

As we approached Denver, we encountered quite a bit of turbulence. I know this can sometimes be the case as I frequently fly this route but not on American. My gripe: Usually a pilot or co-pilot alerts passengers to the possibility of turbulance ahead of time. This did not occur nor did he communiucate during what was a pretty rough ride.

The flight was on time and the landing was very smooth. The crew and flight attendants were all very friendly and professional.

When I booked my flight a month ago - I selected a seat. That seat was NOT the one I ended up with when I checked into my flight the day before. This is the second time this has occurred. So, I checked my next flight on Wednesday and Thursday and no seat was assigned. Poor, very poor customer service.

Cleared standby and gave up my seat. Terrible policy and boarding experience

Message about flight cancelation was received late due to being in the air. No explanation, just canceled and booked on morning flight. We had to stay in the airport overnight because there was no transportation offered to get to the hotel that AA had available. Actual inflight was fine.

Bag drop was very disorganized in Miami. All main cabin passengers were shunted to just a few lanes and they had an equal number of lanes for first class passengers but there was nobody on those lines. They did nothing to bring the main cab and passengers over to the open lines and they just had employees standing there and doing nothing

Flight boarded from Gate 159B, the farthest gate in the LAX Bradley Terminal. While the flight operated on time, the first class cabin attendant made no recognition of my being an Advantage Executive Platinum member.

American Airlines did everything they could with the high Spring Break crowd. I was frustrated to be changed from 1st class to a middle seat at the back of the plane. This has happened before, not sure booking 1st class and paying the extra actually works.
