Forecast your window-seat views
BumpySkies First Class includes cloudiness forecasts, letting you see which parts of your flight will have you passing through or over clouds, and how often you'll instead have clear views of the ground below.
This feature is designed for nervous fliers like me, who feel a little better when they can see the ground, and can even enjoy it when the view is bright and clear. It can be nice to know ahead of time how much of that you can expect.

Nelly says: Clouds hide the ground, but they don't hold any danger!
Flying through clouds is routine and safe, even when it feels disorienting to nervous passengers. Learn more about it on our flight safety page.

It's too early to give you a forecast. I don't yet know the flight plan for this leg of SWA3799, so I can't give you an accurate forecast right now. Come check again closer to departure time. (Note that sometimes I don't know the flight plan until minutes before boarding!)
