The A319's range is 3700 nautical miles when its wingtips are equipped with small fin-like appendages called "sharklets." As of 2011, sharklets are being installed as part of a long-term enhancement program for the Airbus A320 family. The aim of this program is to increase range, payload, take off performance and rate of climb. The A319 has both transcontinental and transatlantic capability.

Airbus states that as part of the A320 family, the A319's cabin is the widest available of any single aisle aircraft on the market. This gives airlines the choice of extra seat width or an extra wide aisle for quick turnarounds.
The A319's digital cabin management system controls functions ranging from interior lighting, pre-recorded messages and emergency evacuation signalling to portable water management. Checks on all service units can be made from a single point within the cabin.
