This Pakistani B777 delayed its departure from Toronto for 15 hours for unknown reason, and took off

Watch as Pakistan International Airlines Flight PK798—a Boeing 777-200LR (AP-BGV)—taxies to the far end of Toronto Pearson International Airport and powers down Runway 23 en route to Lahore, Pakistan. Captured in stunning 4K, this long-haul takeoff showcases the might and grace of the B777 on a 12.5-hour journey across continents. 💡 Flight Mystery This flight was originally scheduled to depart YYZ on August 29 at 9:00 PM, but didn’t leave until 12:25 PM the next day—a delay of over 15 hours. Even more curious, the same aircraft operated PK784 to Karachi on August 31, with another major delay of about 12 hours (scheduled for 12:00 PM, departed at 11:49 PM). I couldn’t find any reason for these delays.
