I just moved to DC from PHL and WN was far more recognizable in PHL than US was.
WN's television marketing is really quite something. For every market they go DIRECTLY after the enfranchised carrier (US in PHL) or after the traditional modes of transportation (i.e. driving the PA Turnpike between PHL and PIT vs. flying WN). I've been in many different markets and have seem customized commercials in everyone. Quite something!
