Hi, I've never heard about air arabia getting out from Alpha...I heard that Alpha will start covering a part of the Cabin Crew training for Air Arabia & 3rd party airlines, Alpha's Cabin Mock Up will be hosted in Air Arabia's new Cabin Crew training facility!
Another news is that Air Arabia has stopped accepting the Ab-initio CPL/IR/TR graduates to give the MPLers some space (they removed the position from the Careers website)...so far (as mentioned earlier) 7 MPL cadets are employed with Air Arabia & another 8 to follow before us (AAA cadets)...don't know from where you heard the news...but its for sure the opposite of what I heard!
I really don't know about the Contract thing...but I know that I will have 40 Sectors with Air Arabia before a Highly Pottential Contract Signiture
