Airline reviews

We boarded the plane and were about to take off when we were notified that the tires had to be checked. Upon inspection, they were found to need replacement, so the entire plane had to be deboarded. After we exited the plane, United staff forced us to stay in the gate area by posting "Do Not Exit" signs on the doors connecting the gate area to the terminal. Many of us had already rebooked our flights and had no checked bags, but they told us we could not leave. This seemed inappropriate to hold people under false pretenses. When the agent told us we could leave, I asked them to please take down the "Do Not Exit" signs, as they were misleading. The agent refused, and I told them that it didn't feel right to hold people like that.

There was a piece of plastic baked into my buttermilk biscuit! I have a pictures. The flight attendants in first class were really apologetic, and tried to rectify the situation. I I am very appreciative that they were able to give me some packets of pretzels and gummy bears. I understand they don't personally handle the food until warming it up so I know it wasn't their fault. I don't know whether it was a newer aircraft, or different food packaging, but I was happy that when the food was being warmed up - it didn't smell like plastic. Jokes on me with finding plastic in my food.

United was excellent. We had very good experience flying the carrier. Certainly. We will opt to fly them for sure. Lufthansa is out.

The seat that I got this time is really good.

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

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.

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.

United has been holding my money for a cancel on another ticket they wouldn’t let me fly for going on 5 months. Terrible service I wouldn’t choose to buy tickets or fly with united again. Very bad experience generally dishonorable and poor service .

The flight got delayed. They forgot to bring the drinks when I asked for it. The toilet is messy.

This was an overnight flight, and in the morning they did know coffee service. How you can throw passengers in a San Francisco airport at 5:40 a.m. in the morning and not giving them Coffee is a crime.

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.
