Out of context, most readers probably wouldn't get this. Whichever airline transmitted this from a 737 MAX9 at or over Portland, it wasn't Spirit - not that kind of "repo". "Repo flight" in this case is repositioning. So who flies MAX9s and might reposition a plane to Seattle's King County Int'l Airport (a.k.a. Boeing Field) #KBFI? Maintenance shops at BFI say they work on biz jets smaller than 737. So this could be Boeing test pilots chatting with flight test base. 👀 #aviation #avgeek
