Re: BACitiExpress The final solution!
With four different types - EMB145, Dash 8, 146/ARJ and ATP, they're going to need to focus on fleet standardisation pretty darn quickly; the 737s will still be needed at Gatwick, so perhaps this is an opportunity for Embraer to prove the low cost credentials of the EMB170-190 series.
Alternatives? I don't think the 318 is an option and the 319 is probably too large; even though it will be a low cost operation, they probably don't want to be replacing a 50 seater with a 150 seater; a fleet of 190/195s, with Embraer taking back the 145s (and as much else as possible) might be the way forward.
