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

11. British Airways – Legacy Systems Meet Modern Headaches

British Airways combines prestige with growing pains. While it’s a flagship carrier, BA struggles with legacy IT systems that have led to multiple system-wide meltdowns and canceled flights over the years. When paired with staff strikes and unpredictable Heathrow congestion, reliability takes a hit. International travelers relying on tight layovers should beware. Booking through travel platforms that offer rebooking support—and avoiding back-to-back connections—can help protect your plans when flying with BA, especially during high-season travel in Europe.
