The team was wonderful. The entertainment screens were not working, so they recommended that we use the plane wifi to watch entertainment on our phones and none of the Delta entertainment links worked. Extremely frustrating process.

The team was wonderful. The entertainment screens were not working, so they recommended that we use the plane wifi to watch entertainment on our phones and none of the Delta entertainment links worked. Extremely frustrating process.

All the amenities was wonderful, if they could keep their prices that low. I'd fly with them all the time.

The WiFi was horrific. I fly delta often and love their (usually reliable and free) WiFi. On this flight it was intermittent and when it did connect was extremely slow. I couldn’t get any work done while I was on the flight which was extremely frustrating. I was also in the exit row seat where there is now immediate seat in front of you, so while the leg room was nice, I couldn’t even watch the TV when the internet wasn’t working. Finally, for the last 20 mins of the flight, the announcement indicator came on the TV screens and took them over, even though no announcement was being made. Really disappointed.

The gate agent was most helpful in getting me on to fly standby. I greatly appreciate it.

Excellent flight and got us around tough weather. Only issue was seat TV did not work and crew tried to reboot.

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

Great - This was the last flight before hurricane closures and did a quick turnaround to get the plane heading north. Much appreciated.

Was unsure of this flight due to high winds in CVG from Hurricane Helene. Crew did a great job of getting us to CVG safely.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Aircraft very cramped. Check-in was great with an agent helping us. Food was almost non-existent. Pre-flight went well once I got the app reloaded on my phone since we don’t fly much anymore.

Flight got delayed for 5 hours no good explanation was offered ;(

Cancelled and declined to find alternatives Earlier flight is 2 days later Sent the cancellation notification very late, wish I knew earlier would have stayed to watch the Miami open final game Very disappointing service

The check in process was a mess for no reason. I spent an hour waiting in line trying to get them to print my boarding pass and as a result I missed my flight.

Four and a half hour delay in total. What frustrates me most is the poor communication and disorganization.

Fecal matter in seat back pocket. Presumably from a kids diaper.

I have come to accept Frontier as an absolute no-frills airline, paying for everything I want. A 4.5-hour flight should provide me with a complimentary beverage—rather, $4.9x for a soda. Or a bottle of water ought to be extended at no cost. 4 beers are on the menu, but only 1 type of beer is available (at $9.95). Also, so many restrictions to using a voucher from Barclay‘s Credit Card. Finally, try to reach a live agent for Frontier- impossible!

The flight was canceled, then delayed twice, we were moved gates twice. Short staff at the counter and check in. We waited for our flight 9 hours. Will never use Frontier ever again, or Spirit.

It's Frontier: low-frills but boarding first because I paid for a carry-on was an unexpected perk, and the fact that it was direct and fast makes up for the lack of amenities.

There was only room for a quarter of the passengers to sit at the gate at MCO. The gate attendant allowed people who did not require assistance to board early before they realized and started to turn people back. The flight was extremely uncomfortable due to pressure. My ears, eyes, sinuses and joints were very painful the whole flight. My sister also complained about her ears and sinuses as well as joints and while deplaning I heard several other passengers complain about the same issues. I’ve never felt that much discomfort flying before and I’ve been doing it for over 40 years.

Got to where I needed to be safely. Thank you!
