I'm sorry. I see I wasn't clear. We only need oxygen in the air, so we purchase it from the airline. It costs $100 Canadian each way. I've inquired with Air Transit and Jets Go but they don't offer this service. We fly from Toronto, and since Canada doesn't have Disabilaties Act like U.S. the disabled don't seem to have the legislated rights that Americans do. That , by the way is the reason we take all our vacations in the U.S. Anyway, we could count on Air Canada, for a price, for oxygen and I was hoping there was some other airline, regularly scheduled service, or charter that might offer this service.
