I purchased a last minute fare to Edmonton, Canada with Air Canada. Excellent pricing made a last minute trip affordable.
I had to do the "Western Canada airport tour" to get there. LA to Vancouver, Vancouver to Calgary, Calgary to Edmonton. Having a disability made this slew of airports a bit overwhelming. But I was pleasantly surprised when Air Canada came to my assistance and helped me navigate the airports,customs and getting me and my luggage to my next flight.
This was not just in one airport but in all of them both on arrival and departure.
Air Canada was a comfortable and clean airline with superior staff and crew. I highly recommend this airline, especially for the disabled traveler.
