How do airlines schedule flights?

How can an airline schedule an arrival time for a flight months in advanced when runways could change and taxis take twice as long and a flight might need to change 180 degrees on approach would could add 10-15 minutes?

Those times are estimated and a “latest-case scenario.” That’s why you commonly arrive early off of your flight.

They use estimation, judging by how long past flights have taken.

Airlines will intentionally allocate extra time for an entire flight.

For example, look at AA21 from London Heathrow to Dallas/Fort Worth.

You will depart at around 11 AM and arrive into the gate at around 3:00 PM. The 10 hours of travel time is a “block time” which factors in taxiing in the airport.

In reality, London to Dallas has a flight time of around 9 hours and 20 minutes:

Airlines will typically land ahead of the time they’re supposed to pull into the gate (3:00 PM in this case) and factor in taxi time:

Of course, airlines can modify arrival/departure times when flights get closer to their departure, depending on the airport.

awesome video… this makes perfect sense. I started to think how airlines would be losing money if they kept over estimating their flight times… but it looks like that they may purposely schedule downtime based on how they operate their connections. This is above and beyond the response i was expecting. Thank you very much!
