I think the CS300 (seats 130+ pax) would fit great between the 717 and the A320/737-800... RA has said he is a big fan of the GTF engine too. The C-Series is in a different league when compared to the E190. With Bombardier's willingness to negotiate for a big order, and Republic's inability to use their CS300 orders/options due to restrictive scope, now is probably a great time to do a deal............ SWISS is scheduled to receive CS100s in the next few months and CS300s 6 months later to fly intra-Europe routes.
