The A318, like the 736, is only good for long, low-pax routes. Regional jets can fly shorter segments with far lower operating costs, or larger mainliners (73G, A319) can fly significantly more pax with only slightly higher DOCs. This leaves the A318 and 736 as niche players, as demonstrated by lackluster sales.
For a few airlines with large A319/A320 fleets that don't want to add a separate 100-seat RJ
, the A318 is worth a look. I don't think it will be particularly successful, but then again, it probably didn't cost that much to develop. Ditto with the 736. The EMB 195 and possibly the FD728 and BRJ-X may shut the double-shrinks out of this market segment.
BTW, communism was never a good idea, theoretically or otherwise
. Marx's assumptions were completely wrong.
Keynes is dead and we are living in his long run.
