the allowability of e-cigs is a gray area and in general unless specifically disallowed (and cigarette bans strictly do not apply) then there is no prohibition. Many entities are looking at re-writing their rules to also ban e-cigs or including e-cigs in the cigarette bans.
Technology moving fast than the rules.
HOWEVER
UA has ban e-cigs (but the FAA or DOT have not)
The use of electronic, simulated smoking materials (such as electronic cigarettes, pipes or cigars) is prohibited on United Airlines.
