KLM seems to be a fan of them - for cargo.

If the Airbus folks push the A318 hard enough to get it in, you can be sure that Boeing will try very hard to place 777 product, with some "intent" to look at 7E7 once they are cleared for pre-sale commitments. Air Canada would need to through something Boeing's way to keep Airbus from slacking off once it totally installed the A320 family.

It's interesting that Bombardier sniffed at and then walked away from taking over the Fairchild Dornier product. That sends a very strong signal that LH was not willing to pay more for a "German solution", and puts the focus on whether Embraer could somehow break in, but that is such a long shot right now. The whole program is in trouble - those 30 airframes that were to go to Swiss were a big part of the order book, and there's not much more to go on.

I would still consider the A318 a "widebody" in that it is a 3+3, versus the 717 which is 3+2 and the RJ's at 2+2. I know it's still a single aisle plane, but the perceived passenger comfort is another factor. Germans do not like the cramped storage bin space!
