Just like the title said....
I've browse the aircraft page and come up with 2 strong candidate in mind. I've kicked out the 32S and 737, can't wait that long!
Well,what do you think?
Depending on how many 732s you have, the EJets could be a bad move, as you'll have to fire all your pilots and hire new ones since EJets use medium pilots and 732s use large pilots. If you only have a few, that's not too big a deal though. That said, you'd want to wait till the E195 for an EJet I'd think.
You could use the 717s as an interim type until the CSeries launches, which would save you firing pilots and buy you some improvment in fuel consumption. Depending on how short your routes are, you could even put HD seating in them and not have a drop in pax compared to the 732 with standard seating. Or you could get in line for A320s or 737s, though at this point you're waiting till '06 or '07 for deliveries of those unless you catch a gap in the line after someone bankrupts.
I'll reiterate that the Avro RJs are a bad choice. They burn more fuel than a 717, hold less pax, have less range, and cost more.
Unfortunately, there aren't a whole lot of other options for 732 replacement at this point in time.
