I booked through Kayak, trusting them. But they used one of these cheap online travel agents - Chatdeals. When I missed my flight due to a 3 hour train delay that was out of my influence, Chatdeals refused to rebook without a fee. SAS couldn’t rebook either. So I was stuck and lost the flight. Had to buy a complete new one. Never book through kayak or one of the cheap ones. Always airline direct! Expensive lesson learned… 🙂 Jan

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.
Reviews
Everything was very good, but my luggage was lost.

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 --
Reviews
Crew members were very helpful, friendly and dedicated. The flight was punctual and inside very clean.

While my bags were left behind, using Apple Trackers I was able to head straight to lost and found and report the issue, they located them in Madrid, and said they would be on the next flight and delivered to my hotel. Great service, other than the left behind bags. It was a short layover, it happens.

Flight attendant for first class is definitely not a morning person. Oh and the WiFi DID NOT WORK!
