Hopefully they’ll bring it back, we’d like to do it again in a few years. There’s still a listing for jet adventures on the
Nat Geo website, so borrowing their jet again would be possible. Fingers crossed, anyway.
EDIT: Reached out to the Adventure Manager for our trip, who gave the official response that the jet trip is “in the vault” at the moment. So, I’m guessing definitely no dates even tentatively planned as far out as their calendar goes.
