29 Airlines Most Likely to Cancel Your Flight (And How to Avoid Them)

28. Air Transat – Charter Roots, Charter Problems

Originally a charter operator, Canada’s Air Transat now offers scheduled flights—but operational kinks remain. The airline runs a tight schedule with limited aircraft redundancy, so if one plane is grounded, entire routes can be canceled or delayed. This is especially risky on seasonal flights to Europe or the Caribbean, where daily frequency is low. Passengers should monitor status alerts closely and avoid relying on Air Transat for time-sensitive trips. Booking with a credit card that offers trip protection is a smart move here.
