Laker, if you consider the new aircraft deliveries as well within the next 3 years I would say you're looking at about 3 to 3 and a half years. Now the DEC issue has slowed down and as I heard from recruiting the only guys they will take are the DECs interviewd in July after they have not given any starting dates to DEC's.
Even if the wait becomes four years it's not bad at all.
My to cents
Cheers and good luck
