Delayed in taking off because no flight crew. The in seat entertainment was working properly.

All fine save for the abominable catering. Really gone downhill. We found it all inedible.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

Flight did not have seat back entertainment and the wifi was iffy.

Pretty standard flight. Delta has a good selection of movies.

The WiFi has been awful on my last few Delta Air Lines flights.

The Flight was delayed in 2,5 hours. 1 hour inside the airplane then we passangers were not allowed to receive food as the local regulariam determines (for delays bigger than 2 hours)

It was fine. no food or entertainment , but was only a 40 minute flight.

The boading process was fine. Had to wait for bus from tarmac to terminal. Had to go through 2 or 3 security checkpoints in Lima to make next connecting flight.

Routine and on time flight with pleasant stewards and decent food. Nice experience!

The crew was super friendly and respectful, they made me feel well all the fly , thanks delta

The seats are getting smaller and smaller. Very uncomfortable trip. More than in other airlines

Check-in was a total disaster, almos a full hour in the line

My experience it was okay but have many thinks to be better. For example the food, the comfort.

Just some cookies and water. There could be other options for food.

For bus boarding, group 1 should have been sent on a separate bus ahead of the general boarding. It would have been nice.

The plane’s radio wasn’t working. This delayed the plane for an hour and a half. Then we all broaded and taxied down the runway only to get called back because the radio was still not working. Had to get off the plane and then find another plane making the trip 4 hours delayed. Maybe a different plane should have been chosen sooner?!?!?!

Flight delayed over 2 hours . I was flying bussiness never got food cause they ran out of what i wanted

Ground staff were excellent They helped to re book when our flight was canceled

The food for long haul was poor compared to Singapore airlines economy. Pasta plain with tomato sauce . Singapore airlines give me Hagen dash small ice cream cup it was great. The choices of dinner course Singapore air also much better The crew mostly friendly. The economy seat are as expected.

Flight was great my baggage was on time everywhere but my bags had been handled ruff cause they got damaged.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

Overall good flight. The pilots were excellent. It was a nice flight, but the seats were a little uncomfortable.

There was no air on the plane and it was very hot.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

Great flight from Charlotte to Orlando. In flight wifi and entertainment was not working til 25 minutes were left in the flight would be my only complaint.

More room. International flight - by the time you put your purse and shoes under the seat in front of you, add in the pillow and blanket they give you- makes for tight fit.

Boarding can be more efficiently done by having the back row passengers board first. This way, the other people do the have to wait for front row passengers to load their luggage in the overhead cabins. Food is simply pathetic for the price I paid. Cleanliness is simply poor; my seat was full of crumps.

Overall good. Tight connection in DFW because of gate unavailability upon landing.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

No food, no entertainment. But the flight was really short so maybe they had to skip drinks. I was able to board early ONLY because I am old and decrepit and they let me pre-board. I RESENT your dumping us into category 9 if we do not pay up. And when I paid for a seat I was STILL given 9. The pre-boarding helps. THIS flight was exceptionally smooth, please congratulate the pilots.

I love to flight american however my carry on had to be sent with regular luggage and it was broken. Don't appreciate that. If when I buy a ticket says I can take a carry on and a hand item there should be space for mwsy stuff and not be basically forced to send the item even if it's at no charge. A.A. needs to work on that. Everything else excellent.

Deparature was late, which is annoying but the arrival was fine and the baggage came early.

Excellent customer service at check in at Austin flight to DFW and excellent customer service from Karren in terminal B at DFW.

The free internet access did not work, so we had to purchase 2 Internet packages. Flight attendants were not proactive in checking in with first class patrons
