It's not related to the A320, but I know that Pan Am International Flight Academy in Washington Dulles has a reduced price CRJ type rating short course for people that have flown the aircraft within the past 24 months.

It was designed for First Officers that had experience in type and were getting furloughed, but wanted to get the type rating. $5,000 for one week of ground school/CPT, 5 sims and a checkride.

If you are interested in the details, PM me. ~Josh
