Could someone please tell me when and where this new segment rule was posted?
There is no new segment rule posted anyplace other than in the e-mail quoted earlier in this thread. And that's the whole point.
The pre-existing LatinPass rules define segment as "any flight which requires a separate flight coupon." Under this definition of "segment," the itinerary I posted a week or so ago qualifies for the 500k bonus.
I leave out of Miami on March 11. Anyone going with me?
