I agree that 1880-1915 was certainly a period of radical change, but aviation in 1915 was way less mature than you are suggesting, and would not become so for several decades.
The SPT Airboat Line [1] was the closest to an airline in the US at the time. It operated 20 mile flights across Tampa bay for 6 months in 1914 before ceasing operations.
Flying from NY to LA was not happening on any regular basis, and took much more than a couple of hours. The first transcontinental flight in 1911 [2] took 80+ flight hours over more than a month. Fast forward to 1933, transcontinental passenger flights took 20+ hours [3]. Nonstops finally became available in the late 40s and early 50s.
