All good……but luggage didn’t make it on the airplane. Had to wait 3 days. Was a bummer.

All good……but luggage didn’t make it on the airplane. Had to wait 3 days. Was a bummer.

Small suitcase used for carryon the last time was refused by boarding crew this time. Appears to be at the discretion and mood of the person on the day. Flight was only half booked, there would have been no problem with space.

They could care less about you. Just under a 4 hour delay in Seattle, leading into a missed connection in Vancouver, which led to 2 more delays that added up to 3 more hours leaving us to have to sleep on the floor of the Toronto airport cause they don't help you find accomodations and they just book you on the next flight out. Took an additional 14 hours to get home. Always given the brush off to get rid of us. Worst airline ever

All was good with comfort and ease of boarding. There was confusion from what gate to board at. Meant moving a long distance but I allowed plenty of time for this.

Good airport. Good entertainment on the big flight. Did not have a good way to prop up or mount my phone/ipad

Air Canada at SeaTac was the best. Polite, helpful, all good!

The problem in part was with the airports, not really the fault of Air Canada. Confusing directions regarding the gate, in Seattle the recommended shuttle train entrance was not working. Simular problems in Toronto. Baggage arrived in good time. Marx Bros movie on entertainment from Seattle. I was told I was laughing too loudly, by the flight attendant. No lounge in Seattle. Lounge in Toronto excellent.

Both fights were delayed. Food could be better comparing to other international flights

I found the personal kind and caring. The Problem was not enough people to serve the the customers. The flow was restricted the crowd frustrated by the wait times. Air Canada seems to hire good people but they need backup in order to provide the service we pay for.

The Montreal to Barcelona flight was cancelled half hour before boarding. We had to struggle for hours to find an alternative route through a very long route with 6 hours of transit time in Munich. It wasted almost one full day of our long awaited vacation. We are extremely disappointed.
