Any possibllity of getting an aircraft code that could be used for the A320 family? Unfortunately, A32* can’t be used to get all of the A320 types flying because of the A319 and A318. (Have to use A31* for those two aircraft.)
Is the A318 considered to be part of the A320 family?
Yes, the A318 is part of the A320 family. It has the same fuselage (shorter, of course) and engines, with a range similar to that of the A319. Interestingly, it’s tail is taller than both the A320 & A319, maybe to give the “shorty” a little more stability in flight? Not too many sold, though. Somewhere in the 30s or 40s, I think. Frontier is the only American carrier w/ them, AFAIK. A’s website has all the info, including the family groupings.
