Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

We paid extra for the seats with extra leg room. But we were not allocated the seats with extra leg room nor refunded the money we paid for the seats.

The flight was heavily booked so boarding was a lengthy process. The FA’s were rather abrupt during this process but became more gracious as the flight went on. Breakfast (puffed pastry and chewy sausage) was pretty horrible but there was fruit and yogurt which they didn’t mess up. Overall it was fine.

Liked nothing. As per previous segment it was delay delay delay.

I completely missed my flight because the first leg was longer than planned. I had to sleep overnight in the airport because no accommodation was provided and then sent to Trinidad in the morning with an anticipated 7 hour layover before my flight to Georgetown which was now with Caribbean Airlines. I tried twice with customer service to see if they could put me on an earlier flight which had seats available but was told it wasn’t possible.

First class felt like economy, seats were horrible, food was horrible, staff inattentive

EVen warmer in the plane it think it was 24+ degrees

The flying experience was great. The flight was on time with no boarding issues during a peak travel period. The short cut baggage drop and process was not smooth and efficient at Dulles.

Fast checkin with the self serve terminal, good communication at the boarding gate.

Very friendly staff. The flight was on time. Need a bit heavy covers/blankets. It can get colder with a thin blanket.

Friendly staff at all very easy check in and organize process

Horrible airline, upgraded to sit on seats made of stone. Staff were rude and on top of it they charge an arm and a leg for luggage 🧳 never again

The seats are the worst I upgraded to premium big mistake and it seems like no one likes there job very unpleasant

they don’t have TV Seat to Type in space

There isn't much space in-between seats and even water needs to be paid for during the flight.

We did not know about the bag fees until check in. They are way too high. It’s insane. We also had a huge delay and everything costed extra which was very annoying.

Lounge for business was closed. Boarding was rush and stand by. Seat for business is just the middle seat blocked and some more leg room.

Flew with our two children. Paid $380 to check two bags (one was overweight). They then left the bags behind on Sunday, December 21st, with all our family’s clothes and family Christmas presents. When we arrived at our destination they told us the bags had not arrived, and they thought (but didn’t know) they were still in Boston, but that there’d be a flight the next day and the bags would arrive the next day. The next day we found out there was no flight, now we’re hoping we get our bags before we fly back out. Meanwhile, trying to get any engagement or accurate information is a waste of time. The folks at the call center are just gatekeepers, who can’t connect with any departments that actually do things to solve a problem. Getting information is made deliberately difficult. My biggest regret is that I’ve had a number of awful experiences with Avianca traveling between the US and Colombia, and still let myself get suckered into buying these tickets because the schedule was great. Never again.

We were not aware carry-on bags cost extra until we arrived at the airport so, we were charged $240.00 for two small carry- on bags! There was a substantial fee for drinks and snacks. No wifi, or other entertainment was available. Waiting areas were crowded and uncomfortable.

I enjoyed it! In that case, I should have been offered this choice. On my first trip to Miami, I was asked to pay $320 for my luggage just for getting it totally broken. I cannot accept this situation at all!!!!

The connection time is too short to pass through customs and once you do clear customs the connecting flight is in another terminal that is not close.

They charged me $120 to check one bag and then charged me another $120 for a carryon. Ridiculous!

Horrible. I have been trying to speak to a representative to know why I was over charged but I get redirected to AI Vianca everytime with no results. Is there an agency that oversees airline gouging? I will never fly or recommend Avianca to anyone not that you care.

I was surprised that they didn’t offer drinks at least even though it was an international flight.

Liked on time, rear entry and exit from plane Dislike the use of duct tape to repair seat rests

They check you everything before entering to waiting room, if you have any liquid they take it away even if you buy it inside the airport, no recommend volaris, for mi know Alaska airline is better

They don’t give anything for free you have to pay for everything which it’s expected but at least give out water and a snack as a courtesy for flying with them.

I got to where I needed to go quickly. There were no amenities. And the seats were painful.

The flight was delayed an hour and a half, and they would not update the board on when the flight was supposed to take off. Once the plane arrived, they started the boarding process before the plane was even ready for the passengers so we had to wait another 45 minutes on the tarmac while we waited for the plane to be ready for us. In my opinion, there is no point in starting the boarding process when you are not ready to board the plane. This just causes a crowded gate with everyone from zone one and zone two standing up going nowhere.

My experience was good. But it seems that every time I go on Volaris the plane is always full, not sure if because the price is cheaper. And the flight attendants kept hitting my shoulder every time they walked by the aisle with their food cart. I’m 6’4” so I barely fit in the seat next to the aisle. Plus the seat was defective. I had a hard time raising the lever where I rest my left arm. I tried calling the flight attendant 3 times if she could assist me but she was too busy talking in the back with her fellow flight attendants. Finally after 20 mins she looked my way and she too struggled to fix the problem but she finally raised it so I could get out of my seat.

Stood inside the plane for more than an hour before take off

I never got an email for checking in for my flight back to Los Angeles so I got to airport extra early to sort it. they changed the gate, and so I had to run to the other end of the airport. Their app is wonky. They are not on WhatsApp and I didn’t have cell service to call for help. I think they need to up their game with communicating.

The app doesn’t work. I am having a lot of trouble checking in for flight tomorrow. Very disconcerting. Then they es t to charge extra for checking in at the airport;(

When booking I was not made aware that my flight would be standby. I was told when checking my bags that I purchased standby tickets. Luckily there was enough room but an unpleasant experience to say the least.

Overall good experience for the price. Thank you for making travel affordable.

Was pleasantly surprised at how large the plane was. Crew very friendly.

Most uncomfortable seating I have ever experienced. And they do not provide any beverage unless purchased. Water was 4.59 a bottle. Same for a soda. A cup of water should be free. I will never fly Spirit again.

This flight went flawlessly. I don’t like thei no adjustment seats and them charging for water… but they’re a discount airline so I guess it’s to be expected

Worst Airplane ride I ever have taken... My purchased seat was changed without my consent

Spirit airlines was extremely uncomfortable. The seats were hard.. the constant up selling (from lack of food or even water to $15 for wi fi ) was annoying. Not a recommended airlines

The seats were comfortable and not as tight as i would have expected. Would have been nice to be able to recline my seat, which was not available. Some form of free snacks and drink option would be appreciated as well, even just a water and small bag of crackers would have been better than nothing at all.

would be great to get basic water, soda at least and stop charging for carry ons

Be quiet! Why do they have to keep talking BS over the microphone?? Enough!

I slept the whole trip but everything else was great
