No Queueing, No Stress
There is no way to tell for certain whether or not your flight will actually depart according to schedule. Even before the entire world came to a standstill, flights could be delayed due to the pilots being too sleepy or whatever, leaving passengers stranded in airports for hours.
What you can do instead is call the airline’s customer service ahead of time. Ask them whether a plane is set to depart on schedule or if it’s been delayed. Doing this will save you several hours of heartache. Call again before leaving to make sure the plane hasn’t been delayed for a second time.
