The DL config for the CS100 will have 110 seats. This is the same seat count as the 717, which has a 12/20/78 split for F/W/Y, but I don't believe the class distribution has been publicized for the CS100. It could be exactly the same, or they could elect to make it a little more W-heavy since it will generally be used on longer stage lengths than the 717. Sadly there's no other comparable configuration in use on the CS100 as the only other operator at this point is SWISS, who have outfitted with in a single class, so it's all guesswork for now.
