what experience does an airline prefer?
Lots if it can get it.
Out of interest, why exactly are you limiting yourself to airlines that fly the airbus??
Because its the best short haul aircraft and leaves you far less knackered after a 4 sector day than any short haul Boeing.
I found the 737 a lot more fun to fly than the A319!
BMRR are you dual rated now? If so how can you say that. Not done open descent at 200kts, then speedbrakes out and go selected speed and wind it up to 330 knots amongst other things? Mind you Ive only simmed in the Boeing and it was far too much like hard work. PS most Skippers I fly with all prefer the Airbus in general but prefer the Boeing in X-wind conditions only...
