Hoping for small compasation for having to rebook my trip back cause i had to miss 6 hrs work

Great setup on both flights except the last flight we got condensed dripping all over me in the last 20 mins of the flight

Delayed for 15 min due to maintenance. We were asked to wait to board as a family, but took longer than if we were not asked anything.

For the amount of money I spent, I definitely expected a better experience

For my third flight in a row on AC 737 Max 8, it was stuffy and warm, especially mid-cabin, Business Class and rear cabin were better. Very uncomfortable 5 hour flight. Do all 737 Max 8 maybe have an HVAC software problem as well or just Air Canada?

The international flights (interior space) is ridiculously small. The aisle way is similar to a discount domestic shuttle. Same applies to the intercontinental flights. The luggage storage space is also incredibly small. The entire experience is rough on a traveler and you pay with your hide and body for not flying let’s say an American or Delta type airline.

It was a very small plane and was ok. No food or entertainment so there should be an option for NA.

I always had the best experience for the professionalism of the crew and the way they make you feel as a family!!!

Terrible, delayed flights lost luggage and lost hotel fees. Missed meetings. Overnight in airport every air canada flight was a cluster mess.

It was good, seating was a little tight apart from that all was well.

I had bad experiences before now was excellent I am glad they have business class again

Horrible experience with Avianca, they delayed their flight and when we arrived to NYC, AVIANCA took 1 hr y 30 mins to park the airplane and all passenger get off the plane, it made me lost all my trains to get back home and I came back to my place at 3 am instead of 12 am. On the top of that their plane seat are so uncomfortable and is not enough space and killed my legs and knees, Avianca used to be good when it was a Colombian company, now after Brasilian company bought them, their service quality is bad and their flights are delayed and oversold.

It was delayed and I lost my connection flight to Cali and I missed my Mom's funeral and avianca lost my check in luggage

It was delayed and I lost my connection flight to Cali and I missed my Mom's funeral

Avianca has transitioned from full service legacy airline to "low cost" but has now became a strange hybrid (minimum leg space, started offering business class in domestic flights again, charges passenger for printing boarding pass, etc.). National and international coverage and destinations are really wide but service is not at its best

Provide free food and drinks on an international flight. Add updated head rests

We found the chairs to be really uncomfortable. It’s also really unacceptable that no form of food or drink is included in a 6+ hour flight

Boarding was late due to the company’s that cleaned the aircraft (very poorly done) and the catering company. The entertainment system was not working for this six hour flight, uncomfortable seats in business (barely any cushion or recline). The airline staff is very good but the planes are horrible and not well maintained.

Deplaning was a mess, I sat in business (seats are horrible) and the front door had a problem so we had to deplane from the rear exit. The stairs were not tall enough to reach so there was a large step down from the plane to the top of the stairs.

Staff are the rudest in the industry … awful customer service … will never fly Avianca again
