The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

Much better than the major US Carriers especially in Biz Class.

I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

It was not Air France but Air Europa. But confusion over our checked luggage. Whether it was checked all the way to Tenerife or not. It was not. Had to line up again in Departures. At least our Sky Priority was honoured. Flight was fine.

My wife and I had a row to ourselves after moving seats. There were no TVs and you had to buy food. So we did nothing but had a quick nap. Flight was fine.

The male attended that served are section was a snob. He did not answer my call light when my wine spilled all over the floor. I did not push it again or drew his attention to it. He just ignored the call light when he came to give us our meal, serving the people behind us first. I did not push it again or drew his attention to it to see his reaction. It was so obvious that he was ignoring us. We were in premium economy!

Georgian Airways check in staff initially denied us, because they thought passengers required transit visas to transfer on connecting flights. This required 70 minutes for them to call multiple people to confirm how transfers worked. They did not apologize once accepting our check in. Onboard, the four hour flight gave stale bread with spam slices as lunch. The only included drinks were still or sparkling water.

I did not get my baggage at my final destination..poor coordination with connecting flights with partner airlines (Saudi airways). Also the food was very mediocre.

There was 2 hours delay before boarding and 2 hours delay after boarding while waiting in the plane

Very good crew. Food service above average. Seats very small for a 12 hours flight.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

Since when do I have to pay for my checked bag? I have a United Explorer mileage plus silver card and I was charged for my checked bags. This also is an international flight. So I would like an explanation to be clear before I choose an airline please?

The flying experience was great. The flight was on time with no boarding issues during a peak travel period. The short cut baggage drop and process was not smooth and efficient at Dulles.

The negative was the wait at the airport coming back. I checked my bags in, an hour before boarding and I get the notification that my flight was delayed. Rather had gotten the notification while I was at the hotel. Then it was delayed 3 x’s. Ugh!

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

Overall good flight. The pilots were excellent. It was a nice flight, but the seats were a little uncomfortable.

I was pleased and I had a very good experience. The staff was friendly and attentive.

Air conditioning in the plane wasn’t working at boarding, this resulted in a delayed departure whilst they addressed the situation. The cabin was uncomfortably hot.

Slight delay but not bad. UA app worked well! Got regular updates of gate changes, etc. Don't have any complaints.

Staff was friendly helpful also good timing I rate it a 10 out of 10

Very crowded; wanted us to check in 1 & only carry on full of meds & supplies; crew very reluctant to approve! I’ve lost checked in luggage in past.. It was non negotiable in my mind!

every single person involved showed their joy, working in the airline industry - it created a very pleasant atmosphere for everyone

Your crew was so so so wonderful Only thing sound be great if you kept some phone chargers and converters rest 👌👌👌👌

For boarding, after family with youngsters, you should have 65 and over. Whatever rules, enforce them. It’s frustrating for those who respect them to see aggressive people rush to the gate out of turn…

AC needs to update their fleet. Too many mechanical issues, dated planes and too many delays

A snack would have been nice instead of having to buy food.

Great service, friendly flight attendants. Boarding was easy. Food was airline food, nothing special but okay. Entertainment was great and overall experience really good. would fly with Air Canada again any time

Air Canada was on schedule, fast, and took care of me the whole flight. With affordable price, I 100% recommend you fly Air Canada if you are able to.

Seats small for international flights, food not good, bathrooms bad, small isles to carry along. For small local flights it’s okay. Emirates had big seats for flight between Dubai to Karachi
