The flight was two hours late due to a computer fault and resulting maintenance. Nothing was offered as compensation beyond bottles of water during the time we were deplaned and waiting in the terminal.

The flight was two hours late due to a computer fault and resulting maintenance. Nothing was offered as compensation beyond bottles of water during the time we were deplaned and waiting in the terminal.

Very pleasant flight attendants. Gate crew rather loud chatting with each other.

Four plus hour flight delay in New York caused us to take off after 11:30pm. We didn’t arrive at our hotel until five hours after check in. Started the trip off feeling exhausted.

Friendly crew. Poor food service maybe due to full flight. All in all, you get what you pay for.

Plane was in bad shape. TV’s and WiFi didn’t work. Plane need a refresh. Not enough room for bags.

Everything was great. I liked the text updates so that I never miss a gate change & I have all the latest info.

I don’t usually fly budget airlines or airlines in the United States. It was as good as any other airline. The seats are comfortable and the airline attendants are not rude & surly. Very nice flight (s).

They have the most inexperienced / rude flight staff I’ve encountered

very difficult boarding process - aggressive passengers not the friendliest crew

WiFi was not eorkig (again) And the plane was from 1990 with the screens which were.not touch and most didn’t even work and if lucky could tune in tv

the plane was not full so the flight attendant had me move to an empty row which made for a good flight. The software for logging on and booking and confirming the flight is much too cumbersome.

Always comes in handy when I want a quick weekend getaway.

For the price I could have taken a “name brand” airline. No drink no snack and constant emails trying to get addition money for EVERYTHING other airlines include in the price. It looks cheaper but it’s Judy bait and switch and emails non stop!

The gate agents for spirit at EWR wouldn’t give me my ticket to board when I arrived 50 min from the flight, saying that I wouldn’t make my flight. They tried to reschedule me to arrive at my destination 14 hours after the original flight, which included a 10 hr layover in another city. I rebooked with another airline and it took me a total of 5 min to go through security. Then I see a charge on my card for a $100 change fee that I did not approve. Beware of this horrible place and these horrible people

Excessive fees for flight delays. What a Scam. I was not able to attend the wedding I needed to go.

Waited at the airport for over 4 hours to board this flight. Terrible airline

Was supposed to take off 8:00 last night. Got delayed till 8:00 this morning

It was terrible, we had to board and unboard the flight with a hour delay that caused me to miss an appointment and a surprise for my wife

When the flight ticket is expensive and you have to purchase check in luggage and there is no snacks, no entertainment, tight seats stuffed in the back of the plane not such good experience. I would like some to reach out to me . I paid for check luggage when I bought the ticket they made me pay again on the return flight extra $70. Very frustrating.

Excellent experience when I am looking for a budget airline where the main expectation is getting me from point A to point B with no frills.
