I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

Horrible. This was not first class. This was a connecting flight whi h was late. My original flight never came. I hated the fact that delta gave me a connecting flight from New York to Orlando Florida. No meals and the television screens were not working. There wasn't even any power to charge your phones. This is NOT FIRST CLASS DELTA!!! Do better next time!

This flight was ridiculous. I had to have a connecting flight from New York to orlando Florida??? The flight left late and because it was a short flight there was no first class amenities. I had one alcohol drink. The flight crew was fine, but it sure did not feel like first class. Delta to me dropped the ball by giving me a connecting flight. By the time we got to Raleigh we would have missed the next flight. Lucky for me the flight never came so now I was stuck waiting for a later flight that came in late also.

Our flight was delayed in Atlanta. The staff could have gave us an explanation for the delay and how long it would be.

I liked the ease of checking in, luggage check in, wheel chair assistance, boarding and flight.

Flight was delayed an no one make an announcement about it., they only have Coca Cola and nothing else., the food that was served was cold… very bad experience and service

On my way home I had a layover. The flight from ATL to CLT was amended 5x while I was waiting. I could have driven home sooner. Overall from Dallas, Tx to Charlotte, NC I started my trip at 4:30pm, I didn’t get home until past midnight. I know things happen, but 5x to make me run back and forth in an airport from different terminals is excessive. I also upgraded to comfort + , I didn’t feel it was worth it. There was no benefit

Overall from Dallas, Tx to Charlotte, NC I started my trip at 4:30pm, I didn’t get home until past midnight. I know things happen, but 5x to make me run back and forth in an airport from different terminals is excessive.

They did a fine job. Can't wait to use Delta in the future.

There was a loud squeaky sound the whole time we were flying.

A disaster, I lost my connection due to overcrowding at the Miami airport, having a 3-hour layover and the airline did nothing to reboard me on time and I had to sleep on the floor for 18 hours.

The food has never improved. It will never improve. But when I'm boarding a flight in priority boarding and I've spent 10 hours inside the security area of the airport and I get "randomly" selected for additional screening as I board the plane when the flight has already been delayed, and I work as a military contractor that has been issued visas direct from JMOD, I find it ridiculous. I would never recommend anyone to use AA on international flights. JAL is a better airline with older planes. The flight attendants on international hauls on American also have a chip on their shoulder and really dont deliver the same level of service code share partners do.

The flight was 90 minutes long and the stewardesses were extremely slow. I was in row 16 and they did not serve us drinks until we were descending for landing in a 90 minute flight. Unacceptably slow and at least 10 rows (20 to 31) did not receive any drinks or snacks for the entire duration of the flight because of the slowness of the stewardesses. There is no rationale to delay beverage service to brew coffee for a flight at six p m.

This flight is frequently delayed. The connections seemingly are more frequently delayed. I’ve missed connections as a result twice on the same route to charlotte then Charleston. Final destination arrival has been the next day, twice in a row. No pilots, no crew. Too many excuses. Unfortunately, my days with American are over.

Entertainment was okay not because anything was wrong but it is a short flight so having no wifi is annoying but understandable. Crew was outstanding as usual

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

The flight was great but board was a nightmare. The gate was changed 4 times during the layover period

The experience was great and much better than the flight going out. of course I was in first class but the service was excellent

Spirit canceled the flight in March and never notified me!

Seats suck, not enough room, overcrowded planes, hectic situation all together.

Pretty good. Would’ve been excellent if we would have left on time and the crew wasn’t late.

I do not like the customer service, I had an emergency and needed to cancel a pet reservation right after I had booked it and they would not do anything but issue a credit. I haven't flown in years as I have 7 kids and don't have spare time. I want my $125 back on my card please

Spirit airline tries to screw you at every opportunity. Spirit wanted 65$ for an extra pound in the suitcase Made me open the suitcase at the counter to remove 1 pound. Staff very cold and rude Will never fly spirit again and will recommend same to family and friends

Delayed..4 times...completely disorganized boarding. After 5 hours they scrambled to move ppl off plane bc they overbooked. Then they didn't have a cabin crew. WiFi on plane didn't work. Zero amenities. Once we boarded we sat on tarmac for an hour. Explore all alternate options including purchasing a pair of hiking boots and walking to your destination instead of flying spirit.

what I like about Spirit is that the pilot and crew are good communicators. The plane itself - well, its a budget airline and you get what is expected, But I generally just feel safer, somehow, when I know more about what is going on - and Spirit has always done a good job of telling me what is going on: why the delay, why the turbulence, why this and that... and that means a lot to me.

I paid just under 200 for flight and luggage, then paid 200 to change the flight, then paid 100 for a carry on. Then the cancelled the flight. Of the 500 I spent they refunded 250. I bought a delta flight for 270 never flew with spirit, but spirit kept 250, not even refunding the 100 for the carry on though they cancelled the flight (for weather on a day with only a slight rain ).

Flight attendants heavily pushed their affinity credit card. Very annoying

They charged me 212.00 for a heavy check in bag at the gate. The pricing and process was so confusing - as if it was designed to purposefully gouge customers who need to board plane. That experience combined with the outrageous price charged will prevent me from ever flying Spirit again. And I’ll be sure to tell the story to anyone who cares to hear.
