Perhaps you want to know what your flight status is so you can keep track of any possible delays or changes that could affect your travel plans—or worse, that would require you to rebook your flight. Or maybe you want to double-check the anticipated arrival time of a friend or loved one’s flight before heading to the airport to pick them up. Maybe you’re curious where the plane you’ll soon be boarding is flying from. Or perhaps you saw a plane overhead and are wondering where it’s headed. There are myriad reasons why you might want to check the status of a flight.
