The entertainment options on the seat back video boards were nice.

The seat was comfortable. There was a lot of turbulence. If it weren't for that,it would have been okay.

First time flying with UA and it was a great experience. Thank you

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

Short flight, crew and staff very efficient. Over all good flight experience.

Teeny tiny bathrooms, crew was not realistic about when we'd arrive.

Check how old the airframe is, some older ones have inoperable seat back entertainment or power.

Gate agent at Frankfurt was terrible. She denied PRE boarding even as it was printed on the boarding pass. Refused to look at the boarding pass and literally shouting for no reason. Frankfurt airport has horrible and rude staff who avoids trying to answer any question at all. Overall, horrible experience.

Flight was late - I was downgraded from first class to coach

Staff on board was excellent. Positive upbeat helpful- like it used to be.

We travelled from London to Halifax. Customer service was excellent.fron the day we booked until arriving. The gate was only a short frombthe waiting area and walk Boarding was efficiently handled and plane took off on time. The service on the plane was very good. Fool an acceptable drandard Only downside was that the legroom was tight for anybody just over 6ft tall and am usually able to travel without difficulty. I will definitely fly with Air Canada again but next time pay for extr space.

Was disappointed when landing in Canada was made to wait for over 1 hour with several other parents and babies for our strollers . The expectation was that the gate checked strollers would be there when exiting aircraft. This was not the case we were told to walk to a point and wait for them . After being left there and not being updated we were met with very hostile and rude air canada staff . There where no apologies or understanding even though all the children where very uncomfortable and the parents very frustrated as you can imagine . Instead the air canada staff at the airport where very rude and made an already frustrating situation much worse instead of trying to assure the parents that that were making effort to fix the situation. One gentleman in particular was very rude to some parents telling them to move when they were simply seeking information. He made the other parents including myself feel very uncomfortable. He also told a gentleman he was capturing images of everyones boarding pass when this was untrue as he was only taking a photo of the gentleman pass which was strange.

It was good, seating was a little tight apart from that all was well.

I liked the flight but the check in was horrendous. I have booked with you before but not ever had to pay extra for luggage, it was not clear on booking, I didn't know there was different categories of economy that meant different allowances. So was alarmed when we had to pay a further £120 at the check-in at a point of not changing.

I wish they gave the earphones earlier rather than when we are already in flight.

Very nice staff members are very nice and friendly helpful

We were a little late pushing back ,but arrived a head of time.

W ended up getting stuck in Edinburgh Scotland during the air strike. They cancelled our flight and No help to get us rebooked. All said down that cost us over $2,000 extra at least to get home. Hopefully we will be reimbursed somehow! Won’t be flying Air Canada again

Very bad, flight was cancelled due to strike and staff was unable to rebook us

The 787 Dreamliner that we flew on was relatively new and a nice aircraft. We flew on a 777 which was noticeably older and the seats were average” but the 787 was very nice, especially for the price. No window blinds anymore, instead high tech adjustable polychromatic glass!! Nice.
