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

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

Late departure. When the flight arrived in Medellin the plane sat at the gate for 20 minutes waiting for a bus for us to get off the plane.

i think the flight was late because they were so strict about measuring everyone's personal items to try and charge them $119. It was really petty and made us late.

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

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

Boarding was somewhat confusing in that the wrong messages were being displayed at the gate. It was somewhat annoying that I got off one flight and straight onto another (from the same gate), but in between they re-checked my hand luggage and made me get rid of my water (which they charge for on the plane). I was sitting in their 'Plus' seating, but the leg room was still too small to be able to sit square. The food options on the flights are pretty cheap quality (but not price). They got me from 'A' to 'B' on-time and for a relatively good price, but the experience itself was below average.

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.

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!!!!

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
