It was a good flight. I would highly recommend it to family and friends.

It was a good flight. I would highly recommend it to family and friends.

The employees were professional and efficient. I consider myself a traveler but have trouble with the international fare served on airplanes. I admit Americans buy their food in the supermarket and we typically don’t eat the ligaments and cartilage. I know that is whiny but as I age, I dislike it more. At least things weren’t covered in cheese. The desserts are terrible! My neighbor didn’t eat her bread so I asked if I could have it. First time for everything but had been traveling a total of 27 hours and was hungry.

The night flight was only 2/3 full, which is always a plus. Room to stretch out for sleeping. Gracious stewardesses, attentive, and slim/attractive (which is rare these days). Good food, and curtesy wine.with meals. Comfortable seats and decent leg room (economy class)

Plane is new and I was upgraded to first class so all was great.

On time service. Seat comfort and the crew service very good .

Only one Hindi movie from LAvto Taipei and same movie from Taipei to Singapore Really horrible and we call it entertainment???

Food was ok. Could have been better. Entertainment was limited, especially for kids.

The flight from Taipei to LAX was the first time we encountered rudeness from the crew. From the gate agents to the in flight crew. We had received such wonderful service going to Bali and on our Bali to Taipei flight that it shocked us when the gate agent was rude and then the rudeness continued on the flight to LAX.

Overall great experience. All four members of my family were seated together without paying extra to reserve seats. Everything was on time. Food was great and healthy. Media entertainment was good. Rock music could be added as a listening choice. No issue with baggages. Flight attendants were friendly and helpful. I would recommend EVA to friends and family.

The crew was very helpful. Food was prepared with great care and tasted wonderful. Movie selection was a bit limited. The bedding on the seat is a little too thin for sleeping.

Everything was awful Flight attendant was condescending, rude and not helpful at all. Small outdated plane. No service, uncomfortable seats. Flight attendant was really the worst. He used hand gestures to communicate instead of words and whenever he used words he was condescending.

Poor and identical to the first two legs, except for the crew who were patient, professional and of pleasant and jovial disposition!

The entertainment would not work. The comfort of the seats leaves something to be desired, pretty uncomfortable.

My flight was completely full. Making me very stressful with people walking around all the time. I believe airlines can do better for entertain people during the flight.

Delayed over an hour due to paperwork not being filed correctly. Forced to change planes.

The departure was delayed by 1 hour. The seat was comfortable and selection of entertainment is very good.

I was refused to used the toilet closes to my seat and had to go to the back of the plane .. it was difficult for me I’m a wheelchair customer

Was a good flight , well served by the flight attendants. Boarding went smoothly, flight was smooth.

Clean and plenty of room for handbaggage. Leg room was cramped compared with the 777 from Frankfurt.

Lady was a bit rude during boarding and I was being nice to her.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

3hour delay In the last 3 months i had 3 flights and 2 of these had a more than 2:40 hrs delayed

My initial flight to ORD was extended without reason. We circled the airport a few time and then drove on the ground for at least 20 minutes. These kinds of delays are annoying but somewhat expected… it would be nice if the crew would make an announcement to give updates on how long we could expect to be delayed.

The flight was uneventful. What was a problem was I was delayed getting home one entire day because the flight from Sacramento was delayed. That made getting to my connecting flight impossible. I had to stay another night at the hotel and incur that expense as a result.

This flight was fine but had no time to breathe as the connection was late from Sea to ORD.. Super stressful. If we checked bags, the trip would have been very distressed.

Seats were very uncomfortable. I paid extra for a seat with more leg room, the seat was no different than a seat at the back of the plane. Flight attendant was rude.

the food choice of packaged chips and popcorn was utterly ridiculous for first class

Check in agent was helpful and nice. Flight was OK. Our flight in Chicago was delayed 8 hours without an explination. This was our journey home. After a horrible flight experience on on the way to our vacation where our plane was diverted for an emergency medical issue, was grounded for hours, we missed our connecting flight by 25 minutes, and it took a day yo get re-booked, this was yet another bad experience that American seemed unwilling to help out with, much less compensate us for the

Late and next flight even later. Who leaves at 245 am and arrives at 330 am ? No wifi, 4 hr flight and one bag of pretzels? AA should be ashamed

No problems on this flight. Entertainment system worked well. On time take off and arrival. Smooth most of the way.

United agent at FLL excellent - due 55 min conx at ORD rerouted us on an earlier departure via DEN and got home 5 hours earlier than expected

Never flew with AirCanada before. Was a super duper flight every time and on time! No changes or delays!

Air Canada seats do not have much room compared to other airlines I’ve traveled with. Also, the lack of free WiFi is a negative. All airlines need to be better about this.

I was mostly pleased. My greatest disappointment was with respect to the timely update to the estimated departure and arrival times. It was especially sad that the arrival time was not updated online once we were in flight so as to allow my wife to arrive on time to the airport. She was not happy.

The space in exit aisle seat was great. Having the entertainment controls in the middle of the armrests is a joke. Your or the passenger next to you will unintentionally push the controls, mainly the sound bar.The placement of the controls need to be on the back of the seats or on the inside of the seats. This crazy placement may only be on the Boeing 737 series but need to be addressed.

I needed to catch a United flight. There wasn't enough signage or help on arrival to navigate the transfer.

Seats weren't comfortable, could have used more let room

Flight was delayed more than 120 min. I had carry on bag but the airplane was full and they had to get it checked in. I had to wait for the small carry on bag at the airport carousel

Flight was delayed 3 hrs, one of the flt attendants was rude to me & I was forced to pay for a middle seat.

Delayed 2 hours 20 minutes. Then we still didn’t take off for another 45 minutes. Arrived in Toronto and no gate was ready for us so we were stuck on the tarmac for another hour. Missed my prebooked Uber and had to pay the cancelation fee plus book another one. Got home over 5 hours later than planned. Awful planning.

The flight landed with a delay and we had to wait almost an hour to be off boarded. So typical of spirit.

The gate employees and the flight crew were friendly and professional. Afterboarding we waited 20 minutes for another flight; a complimentary beverage would have ben appreciated for the inconvenience.

Everyone on the plane was wonderful. I can't say that the trip of flying was wonderful because I hadn't done that since I was 13 years old. Honestly I was terrified. What would make it better is if they didn't drive so fast but I know they have to. And if they could go up slowly and land slowly. But none of that they can control.

Horrible experience, they cancelled the flight , and we had to lose money on car rentals and hotels and tickets for extraction

You get what you pay for, but those tickets weren't cheap, so I expected better, but Spirit is just one of those airlines.

Terrible airline. Cancelled the flight less than 24 hours before the flight. Caused me extra expenses!!! This will be the last time me and my family will travel with them

Very long delay of 6hrs with poor communication from airline. Another 5 pm flight to Miami left on time even though ours was scheduled to leave before that at 3. Would only fly Spirit when you have flexibility for cancellations or delays

Horrible They let some flights go while others where grounded or cancelled. Understanding the storm but there is always a way to get it done when you actually care about the people that are not from the place they are leaving from.

Terrible airline, NO REFUNDS!! Only credit for another spirit flight

Cancelled the return flight moments before boarding, horrible customer service in assisting with any rebooking. Never again will I fly Spirit.
