The type certificate lists a total fuel capacity of 38850lbs. There is nothing in there about optional extended tanks. There are 4 engine options 18k, 21k, 24k, 25k lbs, Delta went with the 21k.
I think I figured it out, at the max zero fuel weight it appears that it can only take around 20,000 lbs of fuel till it hits MGTOW. Looks like that is in a single class 130 seat config. The dual class should get the full 3000+ range.

I think I found the reason. It looks like you can order the CS100 with the 21K engines or the 23K engines. It also looks like there are two gross weight versions, one being max TO 121K, the other 134K, I'm guessing the bigger engines on that one. The website says we are getting the 121K version.
So, there's the range shortfall, can't carry the gas on the dinky engine version!
That also explains all the chatter about the Texas hub, it needs a place to stop for gas!
The DL preview lists the CS300 as having a 2200 NM range, as opposed to Bombardier's 3300 NM number. I don't know. Something seems way off here...

After all, in the unexpected case that issues with the engines prevent the CS100 from operating at more than say 29K feet, its real range will certainly be impacted. Look at the issues with the PW neo, which I think are still operating under a 30K feet service ceiling.
What will be interesting to see is what will the Capex commitment numbers change to once Delta converts delivery position numbers 36 and up over to the CS300--

I think this has to do with the Capex commitment numbers negotiated with Bombardier. My analysis is indicating the CS100 are coming in at between 25-28mm each, based on a negotiated super discounted price based on a paper derate to a 2000 mile range aircraft to replace MD-88's. I suspect that at some stage after the first ones get delivered and ''prove'' themselves, they will be paper re-rated to about 2900 mile range, at which time Delta's Capex commitment for the CS100 aircraft will go up by about 5mm each.

Very interesting information. I think I might have some of my numbers mixed up. I guess we will have to wait and see what the final product ends up being.
