The last Airbus A318 operated by a North American airline has exited service.  The A318, sometimes affectionately referred to as the “Babybus,” is the smallest member of the Airbus A320 family.  Weighing nearly the same as its larger brother, the A319, and operating with the same crew requirements, the economics of operating the A318 in North America just didn’t make sense. The similarly-sized Boeing 737-600 has largely suffered the same fate (although WestJet still operates a fleet in Canada).
