HUH? The 45 is a clean-sheet design and is nothing like the 35. Many operators we spoke with say it's more comfortable than the XL when they and we evaluated the two-if you're tall, the round fuselage of the XL sucks when seated-much less head room. Yes you can stand, but in a 10 inch wide aisle you can't even turn unless you pick your feet up 9" or you have small feet . Anything more than 3 passengers in the XL and you're leaving fuel versus the 45XL where it's full bags and pax. The baggage of the XL is pretty good, however.
