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.

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

It was delayed several hours which delayed our connection in Denver. Not happy.

Ok, but comfort was lacking as the seats were way to small

All good except paid for wifi that did not work

Some of these FA’s need attitude check. Snarky bitches

The plane boarded and deplaned twice before the crew timed out. Flight was 7 hours late departing. Horrible experience!

Got automatically assigned middle seats unless you fork out extra money for a seat assignment, not impressed.

Flight was canceled 12 hours before take-off due to “weather”

The flight was short and that was the best part. The flight was about 90 minutes delayed.

I got upgraded, so comfort was not an issue. But as always, it is the people from baggage handlers, flight attendants, pilots etc. that make the difference.

Good flights. Departure and arrivals were on time. DFW was a little problematic in that the Skytrain without prior notice bypassed the Echo terminal so that delayed my arrival at my connecting flight.

Because I can’t stand very long in one place, I was allowed to reword.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

Excellent- plan was barely populated. I cannot remember a flight where I was able/encouraged to stretch out!

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

Had technical issue which delayed the flight period. Flight crew knew there was 5 passengers that the connecting flight was within 15 minutes once at the gate. Rather than identify the 5 passengers to assure they got first. The flight attended mentioned it but didn't assist to assure passengers with connecting flights off first. This caused a hardship and our party of 3 missed the connecting flight.

Overall it was good but not great. The aircraft was an old and seats didn’t recline in business class unless you kept playing around with it.

I don't like that I have to pay if I want extra leg room. The seats are so expensive; I sit in normal seats and my legs and knees cramp the entire flight. I never feel comfortable on AA flights.

The plane was subbed for another last minute, the gate was changed last minute. Could live with that but we boarded and there was a delay which totaled an hour in the end. There was a technical issue which meant wheels needed to remain out for ten mins after take off. My USB phone charger was broken as was the headphone jack which meant I could t enjoy the IFE and could use my phone after a few hours. Even the map function on the plane failed to work after a few hours.

The flight was delayed and we were told the airplane is on its way to the gate from the hangar. We were told this for 2 hours and the flight was continually delayed in ~30 minute increments. Then we ended up having a new airplane. The issue wasn’t clearly communicated and it left everyone feeling confused about when we would actually be leaving. Whenever they communicated a new boarding time it felt arbitrary and random. The boarding process was a mess and disorganized, which made it last longer than necessary. Landing was rough. Seats were uncomfortable.

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

Delayed several times. Flight was to arrive at midnight and it arrive at 3 am. A 3 hour delay is already bad but one that has you arriving in the wee hour is just disruptive and overall unacceptable. The complete lack of restitution is a joke in keeping with Spirit’s reputation of ranking bottom-low in the pecking order.

Cancelled my flight , currently stuck in Houston and will likely miss my cruise

The flight attendants were very personable, extremely friendly, and had a very good feeling of the energy around them not to mention they’re very funny and engaging. What made up for the discomfort of the seats and the fact that the plane sat for a long time on the Turmac. Not sure if the pilot was new, but the landing was very rough sort of like I was at a magic mountain theme park ride that was built in 1959

Unfortunately not great, my flight was canceled with no notice given. I attempted to reach out to spirit airlines and have yet to receive any correspondence. I then had to book a new flight at two times the cost of the original.

They changed our gate 30 minutes before boarding began. We noticed about 20 people missed their flight due to doors closing early.

Flight was delayed 2+ hours missed a concert because of it…

I MISS MY FLY AND THEY NOT EVEN TRY TO GET ME ALEAST A CREDIT TO BUY ANOTHER TICKET BUT IS FINE I WOULD NEVER BUY A TICKET WITH SPIRIT EVER AGAIN

It’s a flying bus, no reclining seats, entertainment, charge ports. As if someone was out on limb to make my flight experience atrocious

I have been flying spirit since 2012 and the luggage prices are through the freaking roof and the food and drinks are so expensive no one buys them on the plane hardly.

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.
