It was some their customer in Canada, 150 nm in one direction, to pick up an ill person...and way back. They do that trip very often, have both 135 & now 429 ...and very satisfied with 429 ... 30 min difference...with better endurance ... but, as you said ... it can be only Bell marketing...
135 proved itself
, 429 have to do that in future...
