2+hrs delay without any reason provided and a cramped flight

We waited an hour on the runway to get a gate in Orlando

Flight was delayed by 3-hours and their fix was… complimentary pretzels.

Flight was delayed due to crew being not on time

Flight crew issues delayed my flight by 2 1/2 hours. Causing me to miss my connection.

The staff on board and gate was nice - a welcome change from the usual. We also arrived early, which was a great benefit, given that it takes 30 minutes plus to get bags at SRQ.

The staff was frielndly. The plane was terrible, it was too small and should be decommissioned. There were no back seat screens at all. The only beverages we had a choice from was coffee, tea or water. The only bathroom in the back was behind the flight attendant's jump seat and wasn't working. And I literally felt like I was sitting on top of the guy next to me. It was terribly hot in the plane and we had to sit on the tarmac in Chicago for 1/2 hour due to congestion in Mpls. Wouldn't they have know that before they even boarded us so that we could have sat in comfort in the terminal?

Never got on it. Was re-routed through Detroit and am still in airports 12 hours later waiting for my connecting plane to arrive.

Delta has too many delays now days. It is 1:06 am now. I was supposed to land in Norfolk at 10:30 pm. I got re-booked through Detroit and I’m still in Detroit. I hope to be landed in Norfolk by 3am. I’ve been in airports for 12 hours as of right now. There is a weather delay now but most delays lately have been maintenance.

Very Very late. Subsequent flights left an hour before ours

Flight left on time and we arrived 25 minutes early! There was a gate available when we arrived so early on a busy Sunday afternoon! Flight attendants came around twice with the drinks cart.

Wonderful. Quick boarding. Early departure and we arrived 30 minutes early at our destination. Unfortunately, when you arrive early, there is still a departing aircraft at our gate. We had to park for 30 minutes until the gate was clear. So our early arrival was not really early at the gate. Otherwise it was a quick and smooth flight. Appreciated the efficiency.

Flight on time. Excellent service in Premium Economy. Great food served and cleaned up promptly. Unfortunately the climate control was malfunctioning and it was very cold and felt a bit like camping. Cold helps with sleep though so not complaining too much. Slept well. It asks to rate "entertainment". I do not like any IFE, don't shove a big screen in my face—I have my own phone if I want it. So this will always get low ratings.

We had turbulence ever 1/2 hr or so and the captains announcements were SOOOO LOUD

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

it was a very short flight so my expectations were low.

Massimo, flight attendant was very authentic, attentive - wonderful. Food/wrap was just okay.

Worst experience ever. Flight could not land in Charlotte for what we were told was a ground stop. Had to be diverted to Raleigh to refuel. Strangely during ground stop, our connecting flight had no issue taking off on time causing us to miss our flight. We were told there were no other flights that day to our final destination and that two days out was the next one. The only flights to get us there were from Chicago the next morning. Completely opposite direction but it was a direct flight. So we get flown to Chicago and have to find a hotel in our own dime. The flight in the morning was also delayed. Thankfully only a short time. The non too of all this, our luggage did not arrive by the time we were there. Communication was terrible, through the entire trip. Complete incompetence. Will never fly American again.

Horrible. Got delayed many hours because their pilot wasn't trained for night landing at the airport and a rain delay made it a night landing. We have to wait hours for a qualified crew. They give us 12 dollar meal vouchers but most everything in the airport was closed and definitely more expensive than the vouchers.

I am an AA flyer for a very long time... AA has yet to disappoint.

Flight was delayed. Not much information on when the flight would take off. Eventually we were told it was maintenance. App was not giving updates.

Never ontime and always delays. Long waits for customer service and often app doesn’t work

Arriving plane went to wrong gate. Flight Attendant was late. Was in no Hurry when he arrived. Flight was fine. Plane had to wait 20 minutes to get assigned a gate due to designated gate tied up. barely connected.. Boarded extremely late on final leg of trip.

We arrived 25 minutes early only to be told our gate was occupied and so we sat for close to 30 minutes to pull into a gate. That’s not an early arrival!

Experience was great. The best part is the free Wi-Fi connection which helps me to work on the flight

The gate agent had a really bad attitude and refused to help me get on the standby list. She just handed me a card and said I needed to call a number. I asked her to help with the AA app on my phone and she just shrugged and said she didnt know. After a few phone calls, I eventually just went to a different gate agent on the other side of the terminal and got the help I needed.

It was cancelled a few hours before take off. Spirit has yet to confirm I will be refunded for the trip

gate agents with the different rules at the different airports. made me pay for my bag as a carry on instead of a personal item, yet it fit under the seat on the way from Indy to Ft Laud

charging $3 for really bad and cold coffee on airplane flight is ridiculous.

We flew Spirit because it was cheaper but the seats were so uncomfortable. I don;t need to be fed snacks on a plane but when it's a 3-4 hour trip then at least a drink is nice. The flight attendants had nothing to do the whole flight except for gossip loudly to each other right behind our seats, and they talked so much my husband couldn't even rest! I was fine with no tv or entertainment but the seats were so uncomfortable with no recline, no padding, and I am short but even for me to leg room was tough for a 3-4 hour trip. We probably would fly spirit again if we had to, but it's definitely not our favorite!

There was absolutely nothing good about this fight. They delayed us for over 2 hours to give our plane to a flight going to Tampa. By the time we got to norfolk conditions were too bad to land so they took us to Charlotte to refuel so they could fly back to Fort lauderdale. There was almost no communication from the pilot, no wifi, no chargers, and they wouldn't even give us free water when we were stuck in Charlotte refueling.

Checking in and getting to gate fast and leasy at Laguardia airport. There is no entertainment on the plane and food was for purchase. Great experience flying with spirit

The flight itself and the crew were great. Sitting on the tarmac for over an hour until our gate opened up was really frustrating. Missed our scheduled bus and got home two hours later

This flight cancelled. I am in the airport right now and my kids sleep on the floor. We are waiting for information in the line 4 hours and rude woman from spirit airline offers us flight to Austin on 23 February. No water no food offer. The offer to book hotel and they will refund 150$. The nearest hotel 450$ per night. So I got flight to San Antonio 02/22 at 7am. I hate this company, they are rude and no empathy. So many people with kids were there. And I don’t sleep and it is cold here. I don’t have warm clothes for me and my kids. And I don’t have money for transport from San Antonio to my Austin.

It was the most turbulent terrifying flight I’ve ever been on. I will never fly spirit again.

We sat on the tarmac for an hour and a half after landing.
