United airlines, mediocre at best. No issues , nothing great . Worked for me

Boarding experience was smooth. Flight attendants were friendly and helpful. Entertainment system on the Houston-Edmonton flight did not function for passengers on the left side of the aisle. On the bird's eye flight from Quito to Houston, they should not serve a meal. No one needs to eat after midnight and it is disturbing for those passengers trying to sleep.

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

Terrible. Out flight was delayed for 21 (twenty one) hours. United is a joke.

Boarding was mayhem. Late boarding by 15 minutes because of lack of staff (missing 1 flight attendant. We had to wait for an arrival of another plane before we could board). Flight was a little rough, but cannot blame on airlines.

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.

The food was the worst I’ve had on any flight I’ve ever been on.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

Food was edible, not great, and served by attendants who looked like they really were not happy working the flight. The section I was in was too warm making the 11 hour flight uncomfortable. Other areas on the plane were fine.

I’ve never had worse food in business class ever!

Checked bG chstgr was extremely high. Over $120. It was s bsit and switch knowing an international passenger would have t9 check a bag.

First, communication was terrible. The gate on our ticket was not what was reflected on the airport screens and TAP personnel were not present at either gate to answer questions. The flight was delayed and there was no announcement. Also, there was an equipment swap to a smaller airframe which affected our level of comfort. The root of all these issues was as a lack of communication. With air travel in foreign countries already being a stressful affair, lack of communication needlessly raises the level of difficulty.

Checkin was very slow, we had checked in online and hoping we could do a bag drop at the airport. However everyone with checked bags had to queue up and it took over 40mins. Our advice arrive extra early or you will be rushing to the gate.

On time, politeness, food okay but entertneiment mediocre with only old movie and the so called new we’re 2 or 3…

Do you have a bad service And And treat customers terrible

Awful. I told them to cancel my return flight and they didn’t then charged me +$800 days before the flight for a biz class upgrade bid. When I called to confirm cancellation and get refund on buz class upgrade they said I had to go thru orbitz and it was too late. Scammers. Beware.

Little leg room in business. I am tall and could use more.

Was a cheap flight and it got me to Portugal on time. For economy there was ample leg room and the flight attendants were pleasant and helpful.
