The crew were efficient. The pilots seemed professional. It was a bit chilly in our seats. The sheet provided weren’t very helpful.

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Was revoked with Jet Blue due to delay from Kenya Air

The Boarding process was great. Particularly since my wife and I require assistance. The flight attendants were amazing. We travel frequently; they honestly were a cut above. 😀

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.

Ontario airport boarding was very easy to park and access, is clean and TSA took 10 minutes total. Check-in was a breeze and cruise was very nice.

American Airlines II: Delay Boogaloo. Multiple gate changes, delays, boarded and then MORE delays. I hate to say this won’t matter, but posting stuff about major corporations in 2026 is a post-modern “scream into the void.” Was multiple hours late coming home, so there you go.

Awful, tons of delays, I got into Chicago multiple hours late meaning I hit the very traffic I tried so desperately to avoid. Just empty apologies from American Airlines text alerts. Trash behavior from a trash airline.

The flight attendants were very friendly, efficient, and helpful. The plane was ahead of schedule, and it all went very smoothly. Thank you.

They lost my baggage and I am still struggling to the information and update

We got delayed getting out of DFW for broken overhead bins. Once the flight got underway the captain kept the seatbelt sign lit the entire flight despite little perceptible turbulence, preventing use of the rest rooms and any sort of refreshment service in the main cabin.

Flight delays for communication overall not a good experience uncomfortable on the plane. Person in front of me reclined his seat, putting them inches from my lap.

There were flight delays making our flight arrive at our destination after midnight didn’t seem to have enough crew or airplanes for the flights laid over in Dallas should’ve had plenty of time to make it to our next flight only made it because that flight was also delayed because our plane wasn’t even at the airport yet overall have not had a good experience on American

Flight left on time. Captain provided relevant announcements. We had to wait 45 minutes to desembark due to the ramp closed because of lightening.

It's a long flight and that is always difficult. I was comfortable and well. The movies available were great and the crew was good.
