We were in transit from Lima (flight at 1.10am) and we were in stand by in our flight from Panama to Washington. We wait from 4.30 am to 18.30pm in the Airport. The company give us 2 x 15 dollars for eat during the day and a personnal travel voucher of 400 dollars each. Do they buy food one time something in the Airport ??? And one of us live in France so the voucher is not usable. More than 24 hours travel !! And our place were near the toilets, with 8 children around us. The boy behind my seat stamped his feet on my back all the flight. Really Wonder full ! So we are totally unhappy with our travel. Thanks Copa Airlines....

I upgraded myself to Business Class at the last minute so I had a DREAMS window seat. Seeing as I've never flown Business before everything was novel and fun for me and it made the 7 hour flight much more enjoyable for sure.

No headphones given for inflight entertainment. I missed my flight from the previous day and the customer service agent tried to extort an additional $100.00 US from me for missing my flight. Really?!

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.

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!)

Horrible food. No wine or any other alcohol is served on the flight. Water is not served often and they refused when I asked for water in two cups. On the other hand, both going and coming back flights were on time.

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

Our flights got changed from United to Air Canada and our purchased seats did not get transferred so we had to pay for seats twice. I brought it up with Air Canada and they stated I had to go back and chase it with United. The united seats were $21 Canadian each and Air Canada were $56 each so we have paid $77 for each seat. Very unhappy

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

So far so good but food and entertainment are not available for this flight

Multiple delays and not straight answer from the United team

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

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

Paid $35 and not able to access the internet at all.

Several delays. Next flight was worse. Did not arrive home until 2am PT

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

First world problems, but still… We were seated in first class and asked for a cocktail on a very short, 50 minute flight. After our drink order was taken, a half hour went by, and we noticed that every other person in the small plane had been served except for us. We got up to ask about it, the drinks finally came, then were taken away three minutes later since the flight was so short. Really strange situation, on the other hand, we were in Utah.

We missed our flight. The boarding pass had the wrong gate and by the time we received the text from Kayak, our flight was already gone. I’ll never use Kayak again and will go direct to the airlines in the future.

Boarding took forever, the plane was cramped and cold, and the seatbelt song came on constantly throughout the red eye flight with a loud pre-recorded message playing each time

Cabin felt crammed Snacks are lame But crew was super efficient getting us out on time despite delay

Flight was delayed bc of mechanical issue. New plane had different configuration so some seats had to be switched. They called all passengers who needed new boarding cards. They did not call us so we thought our seats were the same and fine. When we boarded they informed us our receipts had changed and we are now all sitting separate and in the back row. Both my daughters had meltdowns and started to cry and once we got on the flight, we figured out how we could sit closer to each other, but this was very upsetting.

Took off on time and successfully avoided weather that looked to be a problem along the way

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

A few years ago long flights 6 hours or so used to have video screens and they offered ear phones. The food cart used to come and drinks. Now absolutely nothing. Avianca is as bad as Spirit Airlines. Avianca will now be my last choice when booking my next flight.

Terrible, We had to stay in Bogota for two days due to weather but the airline did not provide for the same day flight. Only two days later

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

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.

COP 7,000 for a cup of mediocre coffee. I thought I was on Spirit Airlines for a minute. Otherwise the flight was fine. Nothing exceptional to report.

please see previous response; it covers the whole travel trajectory.

I paid over $200 for seat selection for these flights and I was still stuck on long international flights in seats that do not recline and do not have the head support cushion. At this point basically all airlines have those for all seats, and this really took me by surprise and made me not ever want to travel on Avianca. The Kayak agent who called me for the seat selection (Donovan) was courteous, but it seems the system for this doesn't work. I was offered seat selection, for the $200+, but without being able to see what I was selecting, with no guarantee where I'd be...and then I still ended up in terrible seats. On my way to, and especially after, a very intense business trip, the seat situation really soured my experience.

Overpriced checked bag price of $120 and they charge you for carryon if the size is not minimal of $120.

Boarding, crew and food. Seats are too small Love Avianca

I mean, it’s Spirit. But it was frustrating to have our flight canceled, get bumped to a later flight, and then Spirit was unwilling to check our bag until 4 hours before our flight… tell us we could not sit in the waiting area’s chairs… and really negative experience getting checked in and dropping the bag.

Not having it be changed after we bought the flight tickets from a direct flight getting in at a reasonable time to a connecting flight red eye of 9 hours, so that we would lose our 35 dollars in nonrefundable insurance would've been great! Our country really does need low-cost carrier options, but this type of "service" ain't it. Fortunately, had a little better success with them flying to and from San Juan PR last month at least.

All was good expecting the seats need a bit of cushion. Besides that I can’t complain.

You get what you pay for, and the flights went smoothly. There’s no reclining chairs, no screens, And there isn’t always wifi, but the plane was clean and staff was friendly and the takeoff/landing were smooth.

The only positive is that the flight made it both ways. Getting charged for every little thing after the cost of the ticket itself is comical, considering how the plane and services are as bottom-tier as possible. The self check-in kiosks are useless. It’s nice to think that you can print your boarding pass, tag your checked bag, and then just drop it off. But no, they still make you go through the line once you finish- what’s the point of the self check-in then? Any questions for the staff seem like the biggest inconvenience and were met with condescending responses. This was my first and now last time ever flying with Spirit. After all the extra costs, subpar plane and staff, I see no value. I’d rather drive the 13 hours than give Spirit another dime.

The flight was fine however what started as a reasonable priced ticket could have become an overpriced ticket with additional charge for carry on as well as checked bag $79 per bag per person each way. Additional charge for choosing one’s seat, additional charge for beverage and snack, we were on what was described as a new plane yet there were no audio/visual on the jet. A bare bones service but not at a bare bones price. Will think twice before flying Spirit again. 😕

Flight was delayed a bit, but that was expected (and updated), so really not bad at all for the price. Could’ve used one less email asking me to upgrade my seat; otherwise no significant complaints

I love Spirit. New aircraft, great cabin service, the airfares are low cost which helps me visit my hospitalized daughter anytime I can without paying a fortune.

Flight was 2hours late they had no crew or the pilot.

I paid for streaming wifi and the connection was poor.
