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

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

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.

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

Seats in first class on the E175 recline too far back. I was in 2A, and the man in 1A fully reclined almost the entire flight. It took 6-7 inches of space away from me and made it very difficult to work on my laptop.

Mario was great. Made a night flight on a small aircraft pleasant and memorable.

Crew were exceptional. Plane was quiet and quite empty, so I had a row to sleep across.

The seat could use more support or cushion. I'm in my 50's and have back issues so the seats are a bit hard for longer flights.

The plane was in bad condition. We were taxied for mode than an hour because a light panel had feel off. The bathroom in first class had broken panels as well. Overall poor aircraft maintenance

My only real complaint was how much turbulence there was-and that probably can't be avoided. I felt really sick getting off the plane. But boarding was super easy, the flight attendants were friendly, the bathroom was clean. Everything else about the flight was perfectly fine. Thanks!

Caroline (Supervisor) was great! Salute to the employees like her!

The overall flight went well and the aircrew was pleasant.

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

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.

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.

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 felt thirsty and asked the flight attendent for water, but no one came for more than half an hour.

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

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.

ticketing issues caused many customers to have to go back to check in after waiting in security, then go through security line again.

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

The flight was great until towards the end when the flight attendant read an excessively long commercial for purchasing an american airlines credit card. The worst part is that we are doing a lot of traveling this year so i was actually interested in getting the credit card, but I was so annoyed with the long commercial that I completely dismissed the flight attendant bringing around the information. Next time, keep the sales pitch to 10 seconds and then pass around the brochures!!

Nice aircraft. Plane was PACKED full and distance between seats was tight. Had it been more than a two hour flight it would not have been tolerable. I had much more knee space on the JetBlue flight I went out on.

New ridiculous policy by american destroyed my allegiance to american. As a million miler with american, I expected it would be easy to get on an earlier flight when I got to airport earlier than expected, and save a five hour layover. WRONG. The online app would not let me switch flights, So I called, and was promised a call back in 90 minutes. HAH! The customer service desk at DCA said “we no longer have access to changing a flight on our screens. If the app couldn’t do it, I should send a letter to American, but there’s nothing else possible!”

I am tired of being nickel and dimed for seat location, checked luggage and carry on bags. That is why i rarely fly anymore.

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

It was right on time and crew were very courteous

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

Literally the worst experience ever and I had my service dog with me. Flight was supposed to leave at 1:51 PM but the plane arrived late. They boarded us around 3 PM and kept us on the plane for an hour saying that due to weather conditions in Miami, we could not takeoff yet. After waiting for an hour, they deplaned. And then they will not give us our bags back that we could just leave and schedule for another flight. Every hour they kept updating saying we have to wait another hour without any explanation as to what was going on. Eventually, I went to customer service to change my ticket, but by the time I made it to the front of the line, they started boarding my flight again. And then when we got onto the flight, they said there were two flight attendants That were past their shift. They kept us on the plane for about another 40 minutes until they told us they had no other flight attendance and had to deplane again. Then I gave us hotel vouchers and told us we would be on a flight at 6 AM the next day. At this point it is about 9 PM. I get to the hotel with my dog, who hasn’t been able to go potty for about eight hours. When I arrived at the hotel, I got a text alert saying my flight has been canceled at 6 AM and they moved past to 5 AM, however the hotel shuttle doesn’t leave early enough to make it to the airport for 5 AM flight. So me and some other passengers got a cab after about three hours of sleep to get back to the airport. This was the worst experience ever.

Their computers were down upon arrival to the airport. They were unable to figure out how to board us. We were delayed over an hour and a half.

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

Arrived 3 hours early and never made it past baggage drop

Flight delayed then canceled! I will NEVER fly Spirit Airlines again and will tell all my friends!

Absolutely terrible. The boarding process had zero organization. Mobs of people trying to board. People were climbing over my child's stroller with her in it. No families were boarded first. Boarding was delayed with no reasoning or notification that it would be late. We were then stuck on the plane for 45 minutes after landing. Then waited over two hours for our luggage. There was zero communication with the travelers. Never have I experienced such I professionalism and disgrace of others. Extremely disappointed.

For it to have left on time! Instead of two hours early with zero notice
