Absolutely. RA likely knows Bombardier needs a big deal. Add to that Republic has something like 40 CS300 orders and 40 CS300 options that it can't use due to scope limitations. The ingredients for a big deal are in place - but who knows if it will actually happen. The CS300 would be a great potential replacement for the aging MD88s IMHO.

Meanwhile, SWISS and Bombardier are already gearing up for the CS100 (smaller version) introduction in Europe shortly - an initial 12 SWISS pilots have already been sent to training:

The C-Series will be moving forward with or without a big legacy order. I think the initial operating data will be impressive and the aircraft will get more interest. I believe Bombardier should give Delta the substantial discount it is looking for in return for a big order because other airlines will follow Delta's lead. Consider it a marketing investment.

By the way, many people like to cite Delta's previous reluctance to buy "unproven" programs. That is understood. However, keep in mind that if the CS300 (130+ pax) is ultimately ordered, the CS300 shares something like 95% commonality with the smaller CS100 that is certified 6 months before the CS300. So, initial operating experience with SWISS on the CS100 will be very relevant. Again, this is my opinion and completely speculative.
