It would have been better if they don't separate families in seating. We were seated in the aile row in the middle of a family of four. It would have been better if they they seat the family of four together than separated.

It was good, plane is a bit older so seats are somewhat flat

Great from check in all the way to the end. Very happy with Copa

Copa stranded us ans then tried to charge us thousands to leave Panama.

Well the airline was fine. The only thing is I was charged for a checked in luggage. But when I reserved the ticket it showed a check in bag allowed. Who can I get in contact with for reimbursement.? The airline said I had to speak to whoever I booked ticket with.

Friendly flight team and seamless travel from one stop to next.

I loved my experience. Very safe, Very informative and very friendly.

At JFK the Security line was extremely long and few checkpoints open.

Flight attendant -José? - was over the top friendly and professional. Beautiful new plane with lie flat seats in Business (worth it!)

Seats are getting smaller and smaller...and as hard as a rock , mediocre entertainment

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

A bit rush for transit. Food and entertainment are not available

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

Multiple delays and not straight answer from the United team

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

Flight was cramped with every seat taken. The food was fine, nothing crazy to write home about. The plane felt dated and needing some TLC, the button for the window shade didn't work and there were no AC outlets to use. When communicating with staff all except one nice lady never seemed happy to help me almost like I was bothering them when asked for things like a glass of water or a snack. The flight was overall fine. It did what was needed which is get me from point A to point B. But it certainly was not special. I don't expect much in economy but I believe economy on a host of other airlines is more memorable and better experience.

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

I receive a service for what I pay, so it is fair.

Purchased a business class ticket and got a economy seat with center seat blocked they call it business. 3100usd ticket on a flight where economy costs 500usd The biggest scam insult have had on a regular airline. Avianca should be in the low cost category and kicked out of Star Alliance. I want the difference to be credited. Ets see what Avianca does. No reply so far. Avianca = low cost airline. Beware

Business class seats did not lie flat. There was only powdered milk for your coffee....in Business Class!! Food was good.

Excellent flight and one of the smoothest landing I’ve ever experienced

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.

So so, you feel like you have to pay for everything each time

Confusion over extra fees. Held up on ramp during boarding. Thin seat cushion. Minimal leg room.

The check-in is either at a kiosk that didn’t allow me to check-in because my middle name was not on the reservation or at an agent that cost $15.

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

Terrible. And they charged over $400 just for luggage. And threatened that I would loose my flight if I didn’t pay. So I didn’t have another choice but to pay.

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 worst. Kayak sent notification at 2am and 10am regarding the delay. Then sends a notification an hour before original depart time that it will depart on time. I had to wait 8 hours at the airport. My family had to pay for lodging in Guadalajara where I was landing for pick up.

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.
