Had a 2008 Jay Flight 19BH. Wish they never discontinued that model as I like it better than the model that replaced it.
Currently have a 2012 Jay Flight that we love. It's the same floorplan as the previous 19BH but with a front queen bedroom added. Looks like for 2012 that Jayco combined the G2 series (line they discontinued) and standard Jay Flight series, upgrading the Jay Flight series substantially.
For 2015, looks like Jayco downgraded the Jay Flight 26BH substantially basically combining it with a Swift (line they discountinued). It still has a few standard Jay Flight features without the premium package. Premium line adds bells and whistles and brings none construction features back to Jay Flight status but still loses in floor duct heating, and better frame/GVWR.
