Seats were broken in premium select and so was monitored on my seat and other people around me

Read more about Delta

Seats were broken in premium select and so was monitored on my seat and other people around me

Carly the flight attendant was extremely helpful and very accommodating to passengers on the flight from what I noticed. Couldn't be more satisfied with the service and assistance from Delta's flight attendant, Thanks again Carly!!

I didn’t not like that I could not select my seat and ended up with the worse seat.

I didn’t like that I could not select my seat and was assigned a seat when I checked in at LAX

Delta did an awful job w logistics at DTW. Missed connection. We were there an hour early. SUCKED

Inflight entertainment stopped working as we taxi to runway and never worked again until landing and taxi to gate. Grrrr

Flight and gate staff were great as usual. Inflight entertainment did not work. Was watching a movie while at gate. Screen went blank once started to taxi to runway and never came back on until landing and taxi to terminal. Grrrr flight attendants were too busy to bother them. All seats around me were working fine that I could see.

Had to run to make it only to have the flight delayed to wait for all the late connectors Second drink service skipped up

Boarding was a sh!t show. JFK BOARDING was awful. The agent called three sections at a time Clogging the area then yelling at people to not block the walk way. How are you going to call delta one , premium select and comfort plus at once and the yell at highest paying passengers. Need to do a lot better and the flight attendants in the galley need to understand that their voices travel. They were talking about others and everyone in the cabin heard them

Uncomfortable seats on 14 hour flight. Mediocre food. On time and great crew.

The inflight entertainment did not work on a 6 hour flight The cel phone chargers did not work There was a 45 minute wait for the luggage to get off the plane.

Seat space was terrible no food on a six hour flight

There was no bag included in the reservation. The price was double. Not properly advertised

There is no food. There is no in-inflight entertainment. The seats are cardboard. The airline is a living hellscape.

They could offer free food and drink like other international flights.

Delay almost an hour which meant when we got to Guatemala there where 3 flights at the same time, you can imagine the caos in customs, avianca doesn’t care about passengers or schedules

Flight attendants to show up on time, offer drinks and food.

The worst airline, the crew so mean and rude, everything was a nightmare, if I start to write, I'll never end

Pros: "Flight cancelled at last minute still awaiting refund to my credit card. 4270 xxxx xxxx 9954"
Cons: "We understand the problems with cancellations but refund online after phone agent said that was the only way is still missing."
Pros: "Comfortable flight good crew"
Cons: "The boarding process could use help, to chaotic at times but some of the has to do with the countries policies. But I’d give it a B+"

The real big issue with this flight was that it was 3 hours delayed. Other than that, no big praises or complaints.

The flight experience was very good! Especially the United Club!

Overall it was good. The flight was bumpy at times, but the pilot made us aware every time. As a result, no snacks/drinks were made available. Seats were tight but that’s okay as I had a window seat.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

the head jack on my seat didn't work and the power outlet didn't work for my seat

All good except paid for wifi that did not work

Left 2 hours later for delayed I had to take care a kid with special need since people don’t want to move to accommodate the rest of the family. . It wasn’t bad but that made me upset that people can be that selfish.

The crew were really great, but the 4 hour delay in small chunks was the worst.

The crew’s attitud was not good, only worried for pilot’s comfort, so I ask myself why do I pay so much for so less. The plane is old and broken. I will rey another airline

They did get us booked on a later flight, but it made us miss our connecting flight. So, we had to stay and another state overnight with no luggage or clothes. Because they kept our luggage at airport for next flight on the next day.

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.

Everything went well. Got a snack and a beverage.. Able to watch live tv and movies in flight

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

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

Flight was good and arrived a little early. Very good.

IT NEVER LEFT! We were supposed to leave at 5:03 on March 23rd. We were delayed an hour, boarded the plane, delayed again because of rocket launches in Miami, then we were informed that our pilots "timed out" and the flight was cancelled. We were de-boarded and had to find emergency accommodations at this understaffed, un-airconditioned, nightmare of an airport. We were notified that the flight would leave at 9am on Sunday the 24th, when we arrived it was delayed to 12:15pm, we waited in line for over 1.50 to get checked in, during that time it was delayed again to 2pm, then an hour later it was delayed to 3pm, then 5pm, then 6pm, then 7pm. We were told it was pilot timing issues, then rockets, then plane parts, then a mechanic, then weather, then we stopped receiving any excuses at all. There were two flights with almost identical flight numbers 879 and 879P, the AA staff at the airport told half of of us that 879P was cancelled, but apparently it was 879 that was cancelled. They held us in this overcrowded, unairconditioned airport, with no working outlets, and no wifi, for over 8 hours on Sunday. We had to demand our luggage be removed from the plane. For a second night we had to find accommodations. We ended up at a resort that cost over $2000 a night just to find sufficient room for our family. We booked a Delta flight for Monday morning and finally got back stateside with ZERO issues. We're working on getting reimbursement for our expenses which total over $6,000 for the two nights of being stuck there and having to book another airline last minute. IT WAS A NIGHTMARE.

Gossipy flight attendants talked the whole flight about bar hopping and dating.

Turbulence was bad and flight attendants gossiped about going to the bar and dating. Could have better awareness.

When we exited the plane our wheelchair wasn’t there. The Pilot and co pilot were so nice and helped us locate it. Great service.

Didn't like the 6 hour delay as it caused me to miss all of my connections. Still, I did get home safely 14 hours late but exhausted.

3 hour delay was brutal though not Spirit Airlines fault. the control tower would not let us take off because of weather

Beware of all the extras. Nickel and dimed. Everything was extra. It turns a $90 fare in to a $400 fair quite easily.

I flew from Las Vegas to Reno Nevada. Airfare was 60 $ round trip. I needed to bring my skis and boots.that was going to be $111 to bring them. Upon arrival they informed me that anyone who has skis more than 62 inches long is charged an oversize fee of $150 each way. Almost everyone over 5 foot five has skis over 62 inches long. So I paid $60 for the flight and $411 to bring my skis with me! WTF

Didn’t make the connecting flight due to a delay on our first flight.

I like the price. I did not like the seats: very little space and not reclining.

MY FLIGHT GOT CANCELED AND I HAD TO BUY ANOTHER TICKET FROM DELTA TO GET HOME SO I COULD GET BACK TO WORK!!!! SPIRIT SUCKS!! I WILL NEVER USE THEM AGAIN!!

Flights are great except for the ticketing service on the terminal.. Too little employees taking care for lots of flights.

The seats were very uncomfortable. The crew was very polite and helpful.

The airplane was extremely hot the air conditioner wasn’t working I

The text told me it was changed to Terminal E and Gate D5. But with no one on site to ask questions there was confusion on where to go as all the gates were E's. Then we took the skyline to the D area. We left to get something to eat. No announcement was made but my daughter happened to asked and they told her our gate was moved to D12. I will not fly Spirit again.
