This wasn't my experience with Delta. It was just the Pegasus flight. Seats were very hard. Staff was kinda rough. Not very nice. Charged me for snacks. For a 4 hour flight I would've expected more.

This wasn't my experience with Delta. It was just the Pegasus flight. Seats were very hard. Staff was kinda rough. Not very nice. Charged me for snacks. For a 4 hour flight I would've expected more.

Crew was nice, meal was good. Entertainment had to be rebooted 3 times and still did not work. Turns out there was residue on screen, it needed to be cleaned to prevent the touchscreen buttons from continuously activating. I had entertainment for the last 45 minutes of a 5 hour 45 minute flight. Really unacceptable for first class. Flight attendent indicated your cleaning solution creates this problem. Seems as if this is widely known, you should be using a different product or cleaning better. Really really disappointing which simply added to the wi fi on your planes with reliably never ever works.

The baggage belt was not updated on the Delta App and was displayed on the wrong belt board. Was not expecting this to happen.

The plan was delayed and left DC 90 minutes late. However, it showed a 20 minute delay on the delta app, then a 12 min delay. It turned out to be an hour delay. I found out where the plane was with flightaware. Stop keeping customers in the dark about what is going on.

Everything went smoothly, although the usual gripes about airline travel were still present: the boarding process is inefficient, the snack selection is limited, and so on. Since there was extra space on the flight, the gate agent rearranged many people's seats to put people on the aisles and windows, leaving the middle seats empty, as much as possible, which was pretty great.

Landed without a gate ready. Plane is extremely old and dirty.

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

Very old plane with no inflight entertainment. I purchased the internet pass and it was nearly unusable.

My tray was broken so i had no place to work or eat except my lap. Flight attendant said I would get an email with some credit or miles, it was a complete waste of time as I could only function at about 20% of normal. I have not received anything yet.

Short trip, no food and therefore no expectation for much interaction with staff who were pleasant and professional. My critique is on comfort of the seats. Exit rows and comfort seats do not provide enough personal space for 3 side-by-side seats, especially when in the middle row. Some passengers are not considerate of the middle seat and there should be signs that state something to the effect of: "please consider giving middle seats use of the armrests."

No food is available without purchasing it and there is no in-flight entertainment. Both of these are OK because we got an inexpensive flight from Allegiant and, otherwise, our experience was excellent.

just had water and there was plenty of leg & seat room. But then i don't weight 220#s!!

Not totally their fault- screaming kids that had zero parent intervention.

It was cold on the flight. The crew was very pleasant. I didn't order any food. We were delayed due to Captain waiting on maintenance log. He kept us informed though. The flight itself was smooth. I would definitely fly with Allegiant again!

I had a fantastic experience with Allegiant. I had wheelchair assistance and they helped me find my luggage and brought me to my car. Even loaded my luggage. Wonderful service!! Thank you Allegiant!

Superb. Staff great. Great flight. As with other airlines, seating too tight and restrictive.

There is not one likable thing about this airline. It’s starts with the deceptive pricing and continues through the whole flight. The worst staff I’ve ever experienced way over priced bags absolutely no food or drink (unacceptable and you should be embarrassed) the seats are cramped and uncomfortable there is no entertainment there is nothing about this trash airline that constitutes any amount of money. It’s worse than spirit and way more expensive it is disgraceful. Do not travel with Allegiant I repeat do not bother no matter what they say the price is it is never ever going to be the right choice I’m mind blown at how awful the entire experience was I’m embarrassed that I chose so poorly I cannot reiterate enough how beyond horrible this company and its staff are, not one person on this flight or at the airport is qualified to sweep up trash on a city sidewalk they should certainly never be given any job that requires a brain or manners or communication with human beings, what a disgrace to the human race. Your criminal chiselers and should be put out to pasture

Great flight. Friendly staff. Free snacks and drinks would be nice. I would love fewer taxes and fees added on.

My 90 year old father flew with me. He needed wheel chair assistance and is nearly deaf. The staff was amazing with him.

It was fine. Nobody was outstandingly friendly but no one was rude and everything was smooth . The captain thanked us for flying but no one greeted me as I walked on the plane or as I exited which is the least they could do lol

Flight left early and arrived 30 MINUTES early at the destination. Smooth trip.

Flight was 3 hours delayed. They gave our plan to two other routes. Need to knock that off.

The captain announced to the cabin there would be a delay because they observed a "cut" on a tire during precheck that needed to be cleared by maintenance. We were delayed during this inspection and allowed to proceed after maintenance "measured the cut and decided it was acceptable". My complaint is not about the delay or due diligence. I wish the captain had been more generic when making his announcement. I was a nervous wreck all the way to Charlotte worried that we would have a blowout when landing!

The flight was on time and the landing was very smooth. The crew and flight attendants were all very friendly and professional.

Delays experienced in boarding/take off due to incoming plane delayed. However, the boarding time/depart time in the app was significantly delayed in providing these updates. Usually not updated until an hour after we should have already boarded. Poorly managed.

Plane was super cold. No entertainment unless you were with mileage program Getting off the plane was super slow

I appreciate that I finally got the seat I paid extra for this time. Thank you

Half of the TSA checkpoints at PHL are closed. Also, there is no standby for first class passengers. You can only standby for coach. Very dated policy and inconsistent with peers.

It would have been nice if American tried to care.

Delayed initially because they couldn’t print the flight details. Poor instruction on delay. When I got on the plane the flight attendant argued with me about whether my carry on would fit (it did, although she didn’t acknowledge that). No greeting (other than arguing with me) getting on or off the plane.
