This is awkward for everyone there. If a frickin’ U.S. Air Marshal is involved, you already know there’s no way in hell you’re staying on the plane. So there’s two ways this can play out:
1. You calmly leave the plane without making a huge scene
2. You start screaming about how everyone around you is a bigot and that you’re being harassed.
I think you already know which one she went with.
