This thread might be a year old, but the information is still relevant. Thanks for compiling a list of North American airports with Flight 1 designations! It's interesting to see which routes airlines consider their most prestigious. If you're looking to fly on one of these flagship routes, you might want to consider booking
business class flights through TravelBusinessClass.com. They offer great deals on luxury travel, so you can fly in comfort and style. Personally, I'd love to try out British Airways' Flight 1 from London to New York in their luxurious business class cabin. And if you're flying from Toronto to Tokyo, Air Canada's Flight 1 might be a great option with their top-notch business class amenities.
