Whether it’s staffing shortages, a technical meltdown or a weather system that wreaks havoc on schedules, here’s some advice on what to do if your flight is delayed or canceled. If your flight has been canceled, you could save yourself the hassle of a trip to a busy airport. Put your airline and flight number directly into a Google search bar to retrieve the flight status that way. If your flight is delayed or canceled after you've already arrived, make a beeline to the airline agents' desk. Your canceled flight will be covered by UK law if it was supposed to be departing from the UK, no matter who you were flying with.
