The A319 was the following derivative of the baseline A320. The design was a "shrink", with its origins in the 130- to 140-seat SA1, part of the Single-Aisle studies, which had been shelved as the consortium focused on its bigger siblings. After healthy sales of the A320/A321, Airbus focused once more on what was then known as the A320M-7, meaning A320 minus seven fuselage frames. It would provide direct competition for the 737-300/-700. The shrink was achieved through the removal of four fuselage frames fore and three aft of the wing, cutting the overall length by . Consequently, the number of overwing exits was reduced from four to two. The bulk-cargo door was replaced by an aft container door, which can take in reduced height LD3-45 containers. Minor software changes were made to accommodate the different handling characteristics; otherwise the aircraft was largely unchanged. Power is provided by the CFM56-5A, CFM56-5B, or V2500-A5, derated to , with option for thrust.
