Last seat of Bussines Class it does recline but passenger seating behind kept pushing since they did not have space once my seat was reclined

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

No free snacks nor drinks on very short 30min flight. Entertainment system is over wifi to your own phone or tablet, which is good but often a show or movie just stops and refuses to continue

I like the crew they're very friendly. I don't like. on five hour flight they not offered snacks. Any drink. Not even coffee

Not even water is offered on the flight. You cannot lean back on the seats and the seats are so narrow you can’t avoid rubbing elbows with the person next to you.

I couldnt recline the seat. Other than that crew was very attentive and helpful. Thsnk you

I had to go to the boarding counter for them to enter my return flight as it’s not with Avianca. There was a long queue as there were lots of people being called to the counter.

This low cost airline looks and fells more like a local bus. In a 6 hour flight not being able to recline a seat is torture. The only thing available with no charge is a glass of water provided by, mostly, rude staff. Our luggage didn’t arrive

Did not fly with Pakistan International Airlines. Have never flown with Pakistan International Airlines.

Boarding, crew were excellent, food was ok and entertainment need to improve
