Seat back monitors and outlets were dead and not working.

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!

Re-checking our bags, the workers were not able to help us with boarding passes for the flight, told us to wait, then ignored us while they helped many other passengers. Until I got rude, they would have left us standing there, and even then they were very curt and dismissive in telling us where to get boarding passes printed. We made it to the gate just as they were starting to board passengers. It was just rude customer service.

While I received notice that AA 478 was delayed, the flight departed PHX and arrived PHL more than two hours late. The first class cabin service was mediocre; there were no pre-departure beverages offered; there were no warm mixed nuts served with cocktails; there was no personal greeting to me as an Executive Platinum member by the first class flight attendant. While the flight operated safely, its arrival at 0219 in the morning in PHL ended a very long day. I do not feel that American provided first class service.

Absolutely filthy flight and not equipped for a trans US

Turn on the heat. Flight was way too cold from Arizona to Chicago.

Poor on time performance. Flight was delayed due to a lightbulb. No updates from the pilot. Plane was dirty and hot, AC didn't work well.

Being back games on the in-flight entertainment. Also your flight attendants need a break, raise, or overall attitude adjustment.

Overall pleasant was delayed and caused transportation issue when landing

Good over all but my flight from. Miami to Barbados the airplane was very dirty like I have never seen before. It looked like that plane hasn’t been cleaned in a long time and I fly about one time a month.

Flight operated on tie. However, the in-flight entertainment was inoperative. No special recognition as an Executive Platinum member.

They attended to my needs as I couldn't walk and they provided a wheelchair for me.q

On time and fast. Overall it was a pleasant experience.

The weight limit per bag was really low - 40 lbs - so we had to pay extra. Then, they said their carry on size was 14x18x8, and we measured our bag very carefully. It was within the limit, yet they said it was too big, so we ended up paying an extra $100 for that too!! So it wasn’t the cheap flight we thought it would be. Then, they moved up our initial flight to depart 3 hours earlier which meant we had to be out on the road by 7 am and then have a 6 hour layover and we got home at 2am. It was a grueling day. I won’t be flying with them again.

Overall it was a good experience. Stewards were very kind and professional. The departure and arrival times were as promised. Plane was clean.

The seat are terrible. Don’t even think of sleeping on a Spirit flight. The kids that run the plane aka flight attendants are pretty rude and straight forward. They get the job done but without class.

No frills, limited comfort, no food, no entertainment, but fine

I had a death in my family and booked my flight on Spirit. My flight was cancelled the morning of my flight, no explanation, no help to rebook, nobody to talk to. The next available flight was 2days later !!!! Terrible airline, will NEVER fly with them again!

Flight was canceled. Knew there was weather, and were notified of 20 min delayed, and then suddenly canceled. Next reschedule was for 2 days. No help other than to refund. Thankfully full refund and appreciate that. I appreciate discounted airline but felt they could've done more for customer inconvenience.

The seat was very uncomfortable from Boston to Nashville. Otherwise the flight was excellent.

Terrible as usual!!!! Very unprofessional and rude flight attendants! You get what you pay for! HORRIBLE

There was a .79 discrepancy between the cost of the flight and what was paid. Spirit didn't let me obtain my boarding pass until the .79 (seventy nine cents) was paid. Contacting their customer service to resolve the issue was a nightmare that involved many wait minutes and two different departments. The price Kayak gave to Affirm, whom I used to pay for the tickets, and the price Spirit charged for the flight were off by the .79. I almost lost the ticket because of the hassle.

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.
