What should you know about budget airlines flying Canada to the US?
Budget airlines can make cross-border travel much cheaper, but their fares work differently from full-service carriers. On Canada-to-US routes, ultra-low-cost carriers advertise very low base fares and charge separately for bags, seat selection and extras. Knowing how this works helps you compare the true cost of a ticket.
Which budget airlines fly Canada to the US?
Flair Airlines is the main ultra-low-cost carrier operating cross-border routes from Canada, focusing on popular leisure destinations. WestJet sits between budget and full-service with often-competitive fares, and Porter Airlines offers a value full-service experience. The budget airline market changes frequently, so always check which carriers currently serve your route.
How budget airline fares work
An ultra-low-cost fare typically covers the seat and a small personal item only. Carry-on bags, checked luggage, seat selection and changes are all paid extras. Once these are added, a budget fare can end up close to a full-service price — so always compare the all-in total rather than the headline fare.
Are budget airlines worth it for Canada-US flights?
Budget airlines offer the best value when you travel light, book early and do not need extras. For short cross-border hops and flexible leisure travellers, they can save a lot. If you need checked bags, specific seats or schedule reliability, a full-service fare may work out similar in price and more convenient.
Tips for booking budget Canada-US flights
Book early for the lowest base fares, add only the extras you truly need, and weigh and measure your bags in advance to avoid airport fees. Compare the all-in budget price against WestJet, Air Canada and Porter. As with most cross-border routes, mid-week travel booked several weeks ahead is cheapest.
