There is no great time to discover your flight is cancelled but while you're mid-air and flying to the connecting flight is arguably one of the worse times.
Three British Airways passengers had this very experience last week when heading to the British Open golf tournament in Edinburgh.
Raynee Graeff, Victoria Esparza, and Robert Esparza were scheduled to fly from Austin, Texas to Edinburgh via London's Heathrow, according to Business Insider.
However, things took a turn when they received an email from American Airlines saying their London-Edinburgh flight was not only cancelled but could not be automatically rebooked.
"We were unable to rebook your trip from LHR to EDI," read the email, which was sent right after their Texas-London flight had departed.
