5-hour delay due to storms in Tanoa and airspace restricted by Miami traffic controllers.

A regional sized plane was used for a cross country flight with no overhead bin space. I had to "pink check" my laptop and my medications. I was NOT pleased!!!!

Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Best airline! Always friendly and welcoming. Skyclub was great and loved the fast free wifi on board. I also love that you can pre-order your meal on the app!

Atlanta boarding crew at gate were filled with arrogance and were disrespectful. In flight crew showed indifference to the needs of passengers. This is about the flight from ATL to BDL.

The plane was FREEZING SEATS UNCOMFORTABLE Otherwise smooth Thank you

Boarding was chaotic. I didn’t finish dinner because I went to bed early. Breakfast omelet was overcooked and tasteless but croissant was better than usual. Plane was dirty—crumbs in every seam and lavatory was poorly maintained (paint peeling, etc.) and toilet paper had not been refreshed before takeoff. No cubby for storage in first and seat was narrow.

Boarding was somewhat chaotic. Unable to evaluate crew or food/drink because captain kept them seated due to turbulence. Have no idea if entertainment was offered.

Everything went smoothly. I didn’t like that when I booked in the main cabin my wife and I weren’t seated together. One would think when booking on an option that allows picking your seat. They would put you and your travel partner together. Had to call to get it sorted. They did fix.

The overall flight went well and the aircrew was pleasant.

Cathay Pacific seems to be an airline in trouble and on its way out. Lots of broken or poorly functioning things like entertainment screens, seats, and enough well trained staff to handle a full flight. Sad...

The flight crew was exceptionally good. Personal needs were well met. The food choices were very nice.

Excellent. Planes are a little older and could get some refurbishment, but besides that everything was excellent.

Crew experience was more transnational, seats were so close together (LtoR and FtoB) that it was difficult to enjoy much of anything. When the person in front leaned back, there is no space for me. Sadly it was a flight to be endured not experienced.

While I was in great pain, the seat was sufficiently comfortable to allow me to rest and not be in so much pain.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

Not impressed with check in desk staff at Vancouver airport. Not a professional mind service and not cared or tried to help. Don’t think I would fly with them again

Seats were very comfortable. Crew were excellent. Food very good.

Flight crew was especially thoughtful and attentive, made sure our seats were comfortable so we could rest on the long flight

I had back trouble prior to my flight and everyone was great about helping me.

My tv was broken on the flight which is disappointing when you pay for a seat and expect a service

Always delays from Boston to Salt lake but this time was very long. Don’t understand while they board the passengers and then make them sit in the plane

The boarding and flight were ok, but there were several painful issues. The flight was 3:20 in the air and almost four hours door to door, but they only had snack packs on the plane. They really need to have food on longer flights or make it clear to everyone that they won’t have food. They also advertise free WiFi, but it did not work for 90% of this flight. Again, almost four hours door to door. If I had known I was flying spirit for JetBlue prices then I would have planned differently.

Service for food to our seat was a bit slow. Snack choices were just pretzels or baked chips. My seat cushion was not attached. Other than Barbie, video choice were not very good or current.

After we landed, we were held on the plane for 30 minutes. There was no one at the gate once we landed and we forced to sit on a plan that had already over an hour delayed.

almost 4 hour delay as they over booked and had to wait for 8-10 volunteers to agree to travel next day.

Old plane. No outlets for laptop or phone. Seats worn out. Area around seat dirty.

I loved the flight and the crew. It was comfortable and smooth.

The crew was openly hostile and condescending to the customers. They spent the majority of that time in the rear talking and seemed really agitated when people asked questions. I heard five different people told that the information they requested was in the handout or safety brief.

Terrible boarding , Business class seats are sub standard. As usual crew will miss your food too

Just get Economy Plus for international flights, so worth it the extra room, bigger seats…

The return trip was a customer service disaster. American Airlines needs an overhaul of how they treat their customers.

Was flying in premium eco and there were around 5-6 movies I wanted to watch and none of those could I play for some reasons. Not just me we checked w the person sitting next to me. Few of the movies were only playable :( Also that was not great that we couldn't upgrade to business however tried to, many times before the flight :(

You cancelled my flight by email then made it very difficult to get in contact with you. Then put me in a flight with a long layover in Mexico returning to the wrong airport in uk. Mind blowing my stressful. I missed see my grand dad because of you.

This was not the BA business class it used to be. Mediocre food, attendants seemed stretched thin. All the little luxuries that used to make BA business fun were missing. Flight delayed and the explanation given was they forgot to pick up crew - I hope I misheard! Transfer in LHR “sticky” - we thought we had way too much time at 3hours but it was needed. Next time will try different route.

delayed delayed delayed. was supposed to have a 2 hour layover and very nearly missed my connection.

Always getting updates by email very easy to check in on line. There was plenty of checking in staff to get you all through. It was nice that the flight attendants took time to talk to you and were interested in your holiday.

Flight from Phoenix to London was very quiet. Excellent space available for comfort, couldn't fault

Despite a bumpy flight the pilot was great. The rest of the crew on the other hand couldn’t care less if a passenger would colapse and die. Horrible service, robot like, lifeless…

Never been on this flight as i had missed it due to delayed connecting flight

Horrible. Delays, no customer support and fake promises and everything. i am suffering to help as due to connecting flight getting missed no support on ground and customer support window is closed and we are sitting o ground without anything

Missed our departing flight due to poor baggage drop staff. At the airport with 2 & 1/2 hours to spare and waited in bag check in until 15 minutes prior to gates closing before baggage staff asked us to move to the front of the line. We weren’t the only passengers that missed the flight. Poor organizational operations by Spirit staff. Otherwise , the return trip was fine.

My experience with Spirit was perfect. Did not expect it to be this good

Worst airline experience ever. Lost my IPad going thru security. Charged for my dog carriage at the gate not at ticket counter. Gave away my seat 6D. Expressed I wanted my seat back after charging me 99 for dog carriage. Should have thrown it out. Had a 16 yr old Yorkie heading to Boston after being a snowbird. Seats small. Very bad experience. Still don’t have my IPad. Horrible

My mother was HARASSED AND ACCOSTED by the gate agent for her bag. I pre purchased the bag fee and the gate agent made my 78 year old mother board, deplane, re pay for her bag fee and board again. The gate agent made my mother pick up her own bag and REFUSED to help her, she is an older woman who wasn’t bothering anyone on a flight that had maybe 30’total passengers. I am going to sue this airlines for their HORRIBLE customer service and treatment of my mother, and all this occurred the day after Mother’s Day!!!

The boarding gate was moved so many times that I missed my flight. No attendants would help me. The wrong gate was even on my boarding pass. I had to repurchase everything. I’ll never fly again. Really a terrible day as I had planned to see a former student who is dying in Louisville Never ever will I forget that day. Your airline is totally uncaring.

Horrible, first flight delayed. They switched my connecting flight while I was en route and even though I was originally supposed to be on the flight going back home to boston, refused to let me board and told me I would have to wait for next flight that was 14 hours later. Ended up renting a car and driving 6.5 hours back home. Still getting messages about flight and it is now showing that the other flight they put me on is now canceled and I would have to wait 24 hours for the next one. I will never book with spirit again

Hated it I would not use Kayak or Spirit ever again.

They stuck us with multiple extra fees. I will never fly spirit again
