Latest news, Dec 21, 2025: BumpySkies no longer tries to support overseas flights arriving to the United States, due to lack of international flight data. Better international support remains on the BumpySkies roadmap.
It's too early to give you a forecast. I don't yet know the flight plan for SWA490, 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!)
For best results, try it shortly before departure.
(Or, see a random upcoming flight's forecast.)
