Why don't you ask an average passenger what a CRJ-900 or EMB -190 is? Some know, most do not. The price is the decider for most and that is fact.
This US1 will chime in. I AVOID ALL CRJ's and ERJ's (except E170). I would rather connect in PHL, CLT or LGA than squeeze into a barbie or jungle jet.
And guess what? You may think price is a deciding factor....but guess what?! I checked out PIT to BOS nonstop route flying the RJ's. That priced out at $764.70 for the times I needed. Did another search that connected me via PHL and put me on the E-170 & A319 both ways. Only $468.40 for comparable flight departure times.
Guess which one I took?? It sure wasn't the RJ flights.
And your customers are getting wiser when it comes to the type of aircraft flown. Frequent and non frequent flyer types. B)
