Nonstop status not independently verified
The displayed value is a direct-air planning baseline. If your itinerary requires a connection, total journey time will be longer because layovers are not included in the model.
What can make the real flight longer?
Air traffic routing, winds, runway direction, taxi time, holding and airline scheduling can move block time away from the model. Connecting itineraries can be much longer because the baseline does not include layovers.
