Not sure if I've read about her before. Good find ! I plan to give early aviatrixes some smaller roles in my major timeline (in the future), so learning about another one I didn't really know about is very valuable to me.
A real pity she died so young in OTL. A cool scenario would be her remaining in 1920s Europe and becoming a renowned emigrant pilot in her own right, perhaps even in the nascent air circus, aerobatics and exhibition flying entertainment industry. In such a situation, I could imagine Coleman earning some extra money during her stay in Europe, as a sort of female version of
Samuel Cody or similar. Loads of surplus biplanes and retired pilots after the war, so post-WWI Europe and North America took a pretty big liking to this new, aerial form of theater. It was rather huge during the interwar years, and much less regulated (and more dangerous) than the nowadays more familiar post-WWII style acrobatics and theatrics.
Later on, from the late 1920s onward, she could maybe try her skills at setting new aviation records. Though those were all the rage already before WWI, the interwar period saw a lot of new effort in attempting long-distance, endurace flights with the then-available technology. The first trans-Atlantic crossings, the first aerial circumnavigations of the world, the first flights over the poles, or the Amazon and Congo, or the Alps and maybe even the Himalayas... Plenty of oppotunities for geographic exploration and tech-enhanced heroics of a new kind. It would be interesting to see whether her and Earhart might develop something of a rivalry in the field of record-setting flights in such an interwar ATL. Earhart perhaps held up by some as the "American who stayed at home", while Coleman would be seen as the "American who went abroad, but also struck luck". Bessie's overseas successes could maybe also prompt some US rights campaigners and education-encouragers to petition the government to desegregate at least some aviation-related learning facilities.
