Flair Airlines, known for its budget-friendly domestic routes, permits reservation changes up to 2 hours before departure, though change fees may apply depending on the fare. Porter Airlines provides seamless short-haul travel with complimentary onboard snacks and flexible modification policies, especially for Premium fares, though name changes are generally restricted. WestJet Airlines offers a wide range of fare bundles, and most bookings can be modified online, with flexible fares like EconoFlex allowing free changes. Across all airlines, it’s crucial to review fare rules before booking and consider flexible options if plans may shift. Most airlines offer user-friendly apps and websites to manage bookings, receive real-time updates, and access travel credits or rebooking tools easily.
