Well Ive flown alot of Airbus flights mainly on A320/321 but I got my first go on an A319 earlier this year when I took Germanwings to CGN and back.

To be honest there isnt much difference from its brothers but it is noticable how short it is from the inside.

Overall I enjoyed my flight on it and as you can see from my signature my next 2 flights will also be on A319s.
