So DND could take a 318 or E70/95? Given the existing LCY route, would BA move around a/c just to serve this and maybe one or two other places (GCI)?
Ah ha. You forget the dreaded unions, who wouldn't allow it just to be sticks in the mud. Otherwise Cityflyer could expand through the roof with 195s and replace the 737 operation at Gatwick rather smoothly.
