Maybe... But I am not sure if anyone is building them anymore. Didn't Fairchild-Dornier have financial problems and close up shop? Also, I think US wants 50 seaters, not 32 seaters... If Fairchild is still around maybe the 428JET program makes sense? Maybe they are closer to 50 seaters. In any case, my bet is that U sticks with ERJs since all of their Express carriers who fly RJs fly ERJs. Just my guess though.
