As airlines face pandemic-related staffing shortages, flight cancelations are ruining vacations and stranding passengers. So, what can you do to protect yourself? The only thing worse than a flight delay is a cancellation — except when it comes to getting your money back. Angie Barnett, president of the Better Business Bureau of Greater Maryland, said there are no federal regulations when it comes to reimbursing you for delays. Cancellations are a different matter, and Barnett said putting everything on a credit card is key — not only for documentation, but because your credit card company may afford you more protections. And, if you have to rebook, Barnett said to go online.
