8.0 ExcellentCarl, Apr 2024JFK - FLL
Read more about Delta reviews

Seat back monitors and outlets were dead and not working.

Everything was great except for the seat. The backrest would not stay in the upright position.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

Flight delayed about 2 hrs so it made it a VERY late night

It was a crowded flight. They did the best they could.

Service was good for such a short flight. Small plane but smooth flight.

Worst flight in my life. Only was scheduled for a 45 min flight to get our connection flight. It was late by 40 minutes and we missed our connection. Delta was totally useless trying to help and unable to get my family on the next flight because they overbooked it Thus had to get a hotel at my expense and lost a day at Disney as a result. Cost me about a $1000 if you add 2 hotels meals shuttles etc to get thru the day Awful customer service by Delta in Detroit totally useless people

The experience was good and the flight departed on time and landed early

The flight was delayed but we got to our final destination.

Boarding was great. The flight landed early. It took the crew over an hour and a half to bring out drinks. I paid to upgrade my seat to Comfort+ only to be near a crying/screaming baby who was seldom quiet. Noise-cancelling earbuds didn’t even help. Waste of money to upgrade.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

flight delays, staff only communicating when pushed, food service lasting a grand total of 7 minutes, stuck in seat from 45mins into flight until landing

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

they made me check my carryon. There was space in the overhead bins.

Nice flight, nice crew but no cookie or napkin with my seltzer.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

I liked everything about the flight. The service was excellent!

i suspect i caught flu on this flight as i could hear someone coughing a few rows back and ended up with flu a few days later. also tiresome to have to watch movies on my device by holding up smartphone screen, would have liked to have in seat display.

Plane took off without me, my stepdad and a dozen other passengers. It went from an hour delay to boarding in 15 montures without notifying anyone. Names were not called overhead. Now I’m missing a day of work and stuck in Charolette overnight paying for a hotel and Ubers out of pocket

The flight was fine. All the delays and poor communication and customer service were the worst! We were supposed to arrive in London at 7:10 am. In stead we arrived at 1:30 pm. And now American Airlines refuses to make things right but only sent a canned apology after I contacted customer relations.

The flight was delayed for over four hours due to “maintenance “. Your ground staff made no efforts to avoid my family missing their connecting flight to London. They did not try to reroute them and didn’t even offer meal vouchers without being asked. My daughter, her husband and four children were in the States for our son’s celebration of life service. They experienced rude and unhelpful staff in Asheville. The lack of communication was disgraceful. They missed their connecting flight and the first rebooking. Then the 2nd rebooked flight was delayed by over two hours. They didn’t leave Charlotte until 1:30 AM. Since returning home my granddaughters sleep has been so disrupted that they are overly tired and cry hysterically at bedtime. I have already contacted you regarding compensation but have yet to receive a response. All I’ve received is a canned wrote response. This is not acceptable!!! When my wife and I traveled to England in December on your partner, British Airlines, we were delayed for 4 and one half hours. We missed our connecting train to Leeds and had to pay double. They not only reimbursed our extra train expense, they also refunded half our airfare. And upon our return to the States we were surprised to find that they had upgraded us for free! Now that’s customer service!!! I look forward to a prompt real human response. Sincerely, Jon Cannon

We sat on the plane for 1 hour because the airline was short handed could not be unloading.

Flight delayed 3 times. We were directed to go to a gate across from our gate. The plane wasn't there yet so we had to wait for it to arrive, then deplane everyone and then wait again for the plane to be cleaned. After 45 minuites we were allowed on the plane. The first plane had mechanical issues. The 2nd plane must have had bathroom issues because we did not have any food service whatsoever. No snack or beverage. That made for a long time not to have anything considering that we had just made it to the original gate and we had no time to stop to get food or a drink. Then we didn't want to leave the gate to get food because we wouldn't know how much longer the delay would be. Then the next gate change. Had we been told that the total time would have been aprox 45 min later we would have left to get food and a beverage. We had to wait again for the okay to the pilot to take off so we were on the runway for another 20 min. Overall, we were delayed over 2 hours which felt like 4 hours.

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

Flight delayed, boarding time kept changing, not good. Nee firm information given each time.

I had trouble finding a boarding pass because I had an hour between Flights and American did not see my flight I believe because I was ticketed through KAYAK. I did not have enough time to go to the desk before boarding so I went to the desk and told them while I was boarding and they had a boarding pass for me within three minutes. Nice. I paid extra to have more legroom and it is definitely worth it for a six hour flight. I would’ve paid for a decent dinner, but they didn’t offer anything but a snack box —not good for six hours.

Charlotte airport is miserable. For American I always have to connect from the end of terminal E to the end of terminal B and the stupid moving walkways are always broken. And the flights to all seem of least importance so they never leave on time in either direction.

Not have to pay for every single item to take a flight. Seating and delays sucked.

Flight was cancelled and I had to spend the night in the airport lugging my suitcase around

If you don’t check in 24 hours in advance, they will charge you $110 to check your bag instead of the $30. I did not get an email with this information and did not check in. In addition, my flight home was cancelled at layover and I had to spend the night in the airport, and then have another layover at another airport before making it home. Will not fly frontier again.

Terrible. Seats are bad and the baggage policy is inconsistent

Flight delayed 3 times, resulting in late arrival, rental car place gave car away resulting in increased BS charges because I was late. Frontier blows.

I paid for extra leg room. The flimsy plastic seat underneath the floatation seat did not line up with the arm rests. It seemed as if the plastic part was zip tied on but immovable. This caused severe uncomfortable for the duration of the flight.

Left Denver late, then sat on tarmac 30 min after arrival

Better than I expected but I did pay for a seat and carry on bags ahead of time.

Crew members are very rude and not cooperate with passengers.

30 minute delay due to boarding and settling of a family.
