FA was a bit strange and dodgy not very characteristic of Delta

We departed early and made up time in the air allowing us to arrive 30 minutes early. Capt was incredibly genuine and thanked every passenger for flying with Delta. Completely humble and professional!

The boarding process needs to be refined. Sometimes the gate crew calls out the zones and then flip to showing the.zones boarding on the gate monitor display. So, unless you are huddled around the gate lanes watching the monitor, you could miss your boarding zone. Suggest the zones be announced each time a new zone is allowed to board.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

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

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

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

The boarding announcement was hard to understand and I almost missed getting on board because of the garbled announcement.

As we lined up to board they gave our plane to a flight going to Newark. So then we got delayed until they could find another plane. Flight crew was ok. I’m assuming since it’s a shorter flight they only offered water and coffee.

We called Kayak for a change due to the TSA situation in Atlanta. What we got was a canceled return flight (in error) and we had to find the mistake. Not happy with Kayak who blamed it on AA.

Small plane, poor meal choices for first class, bad terminal and boarding experience at LAX

Boarding delayed 20 minutes for no reason, no wifi, in flight entertainment, or snacks / waters?

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

Improvements in communication and empathy are absolutely necessary for American Airlines staff (top down). It’s like they are numb to the needs of their customers.

I like the speed of boarding and deplaning and the fact that everything was on time. The crew (attendants) were probably quite new and did not begin the in cabin service until 30 min before landing even though there was little to no air turbulence for the last 1.5 hours of the flight. It made for a mad scramble at the end to get trash collected and carts stowed before touch down.

The flights was delayed by hours and it was the firmest landing I have experienced in my life. My back is still sore.

I did like the employee's, they are very friendly and all smiled most of the time, Overall, from checking in bags to getting on plane, not enough employees to be able to get all on the plane, therefore I was not able to get on the plane, due to no one wea there for me to check in my bag, so I decided to go thru the security point and by the time they were done with my bags, I was told that my bag cannot be checked in, and then found out that the lady that does the check in was boarding the customers onto the plane, she said that she was going back and fourth, there for was not able to get on the plane, which changed all my flights by the time I got to Dallas, I was on standby 3 times, and wasn't sure about being able to get on the fourth plane, so ended up buying another plane ticket, so I could make my destination on time.

Not sure about entertainment as I didn't use any, so maybe there should be an NA option on this survey. Otherwise everything was just as it should be. Of course I wish planes were more comfortable and had seats that would tilt back further.

American Airlines “Randy” questioned why I needed preboarding and denied my request for same. Then Randy attempted to berate me when I boarded with my group. I was seated in an exit roll with a young man with a disability that exhibited difficulty controlling and settling himself. But Tandy questioned my disability. The flight was horrible. It was overpacked.
