The trip was beautiful and the Icelander crew was very helpful with us
We boarded 20 minutes before the actual boarding time. The plane left on time and arrived a little early. Air Canada's crew served 1 drink service during a 4.5 hour flight, with no snacks. It's a good thing that I have access to lounge service.
My luggage got delayed, trying to reach out the airline and no updates for me where my luggage is and when it will be delivered to me.
Pros: Crew was acceptable but sits terrible
Cons: Not a comfy flight
I’m not a fan of the CRJ aircraft.
Considering I cancelled the flight 2 months ago -- I would have to say the communication was poor -- since I continue to received updates. I say poor since Kayak seems not to want to respond to me to reschedule a flight -- they hold my voucher -- so I can not do it on my own --
Wrong advice was given by AF counter for the boarding by asking me to exit airport and then enter again , otherwise was ok .
Flight attendant for first class is definitely not a morning person. Oh and the WiFi DID NOT WORK!
