Your Flight

We analysed more than 2,000 data points along your route from Washington Dulles International Airport, Dulles to Nashville International, Nashville.

Your Journey Beta

Some bumpy patches are scattered throughout the flight. Keep your seatbelt fastened when seated.

Your route takes you over the Appalachian Mountains – conditions there can sometimes cause light turbulence.

Mostly Smooth

Overall conditions look mostly smooth with occasional light bumps. Nothing to worry about.

Takeoff

Takeoff should feel smooth with possible light bumps, with calm conditions around the airport.

Winds Aloft

Winds at cruising altitude are about 93 knots. These winds may delay arrival by up to 15 minutes.
