Yeeaaaaaaa..... let's trust the one source, that if we used it for say "education" we'd be given an automatic "F" for citing it as a source, ya know... since Wikipedia can be altered and such. Now if you wanna use a reputable source, why not try "Britannica Online" which has a nice piece on Public or "Mass" transportation, and unless I skimmed it entirely, it does not say anything about air travel, but please correct me if I am wrong. (also the site might give an annoying pop up every few seconds asking you to join up, but you close that and continue reading)

to quote a phrase from the article:
Quote:
mass transit also called mass transportation, or public transportation
the movement of people within urban areas using group travel technologies such as buses and trains. The essential feature of mass transportation is that many people are carried in the same vehicle (e.g., buses) or collection of attached vehicles (trains). This makes it possible to move people in the same travel corridor with greater efficiency, which can lead to lower costs to carry each person or—because the costs are shared by many people—the opportunity to spend more money to provide better service, or both.
