UA594 was delayed multiple times. I ended up getting picked up so I can make it in time for work 6AM on Monday, 7/6/2026

Monitor control didn’t work & couldn’t figure out how to lay bed flat so I slept very poorly. Cabin was very cold

Excellent flight. On time. Great staff. Clean and crisp cabin.

The airline was fine, but I did want to share about Kayak's error through Underpricer. The original booking was purchased with ANA, and Kayak booked it with United. This is a mistake that should not be happening, since the price I paid was with ANA and that was my preference. I appreciate the efforts done to make this right by paying for the seat preference, but sitting in the back of the airplane under economy is not enough to make this error right. ANA Airlines was the experience I wanted considering this was a life time experience that my family and I wanted to have as part of our Japanese experience. Please work on your affiliation with Underpricer to make the right bookings that the customer pays for. In my situation, I could of paid less for a United ticket versus my original payment with ANA Airlines.

The Manila airport was under renovation so there was no business class lounge. The double security check was disorganized and the flight attendants were grouchy.

Know that the movies that you are going to be offered are the oldest be rated movies they could possibly get. They may have one or two new movies that they keep advertising but when you’re flying 15 hours, there is nothing to see past the first new movie.

Flight attendants on United are the worst in the business. Can’t be bothered to provide even basic levels of service and are as rude as anyone can get. This flight was not an exception to that rule.

Friendly crew, but we were delayed for more than an hour and had to change planes due to maintenance issues.

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

Very good service and very helpful support staff (wheelchair service)

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

The fees for baggage were outrageous. $130 for carry on and $150 for check in for an international flight. The seats did not recline. We were not even offered water. Had we known all of this, we would not have booked Avianca at all.

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.
