A flawless trip, great experience. Keep up the good work!

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

I handed in my suitcase in perfect condition at SAL Airport. And in MIA Airport I received it with one corner broken and the wheels bent.

It was horrible. My experience with Avianca. I didn’t know it was Pakistan international Airlines but anyway, whatever it is it is bad horrible you guys need to upgrade everything in those planes. And you guys charge $130 for a carry-on did they wanna let me in with my carry-on that I travel everywhere with the luggage you guys are such a dog thank you

I was shocked flying to El Salvador that they only give you water. Everything else you have to pay for. There is no wifi or entertainment and it’s an international flight. At least back in the day they had tvs on the plane and everyone watched the same movie. Also seats do not recline, even comfort or plus.

The good thing is the flight was on time and the crew was really nice. They can work better the arriving with staff

The inflight entertainment did not work on a 6 hour flight The cel phone chargers did not work There was a 45 minute wait for the luggage to get off the plane.

They could offer free food and drink like other international flights.

Delay almost an hour which meant when we got to Guatemala there where 3 flights at the same time, you can imagine the caos in customs, avianca doesn’t care about passengers or schedules

Flight attendants to show up on time, offer drinks and food.
