The food is terrible. The same pasta or chicken with bad taste and presentation

It was probably one of the worst flights I’ve been on. The restrooms were never cleaned or stocked. The food was very subpar, and i usually enjoy airline food, so I was disappointed. It was just all around a bad experience. The only saving grace was the flight attendants.

The only downside was my cell phone charger wouldn’t work in the charging port but everyone else’s would work in them all. My cell phone cable works fine in my hotel room in Frankfurt.

Great crew, excellent landing, good food. Over all great experience. Thank you!

One bag is incorrect and not acceptable for an international flight. The food was not just good. I won't fly with them again.

Not pleasant trip cross country when the entertainment and WiFi system not working. No entertainment for entirety of route. Staff was rather nonchalant in that they dismissed the problem due to age of plane. It would have been nice to know this up front so I could have come prepared to read or download movies before boarding Coincidentally or not, there was a similar issue with the entertainment system on my previous flight I took on my fist leg of the trip. There are no seat TVs, so you must rely on the app when it works. United can do better. Also, what use it it to pay for boarding group 2 when half of the passengers are in the same line as you?

Crew was dismissive. Snacks and refills not offered. Poor business class experience. Bed not comfortable compared to Emirates or BA.

Flight was delayed for 5 hours because crew didn’t have enough time to rest - this seems like it could have been avoided with better scheduling. Food was not good.

IAD with the archaic people movers is just a place to be avoided.

Overall, it was good. I was seating next to a wonderful lady and did not notice how time flew. Thanks

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.

I like the crew members they're very friendly. Clean plane. The flight was on time. I dont like the comfort my car seat its better that the plane seats. They charge for everything. This airline was very good. Now it's a low cost airline

6 hour flight and have to pay for everything 100 dollars to add a carry-on bag is insane

Usb plugs for charging your phone does not work in every flight. uncomfortable chairs even in higher categories.

The check in is the only positive thing in Avianca. The seat is the most uncomfortable I have traveled, the distance is minimal.

Not what it used to be. The sale of food makes them look greedy!

Avianca is not what it used to be. So disappointing

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

why did we have to go through security mid flight

The chicken that was served in business class was cold!
