It's impossible to say anything definite. After all, who can imagine any other country where the aviation authority interferes so much with how an airline actually conducts its business, rather than sticking to its job of looking after safety. Add that to the government sticking its nose into every aspect of a private company and you can see it's pretty difficult saying something will or won't happen.
However, the rumour mill has two optimistic predictions. One is the ANA pilots union's dislike of all things JAL. It has been said that they would much rather have western pilots flying ANA aircraft than the Japanese pilots of JAL. This is third hand but allegedly from a very experienced Japanese ANA pilot, with a finger in the union pie. Who knows how true or false but this is a rumour network!
The second offering is that AJV still requires another 80 pilots. We've got another 2 aircraft arriving this year and then the final one of 11 arrives early next year. Couple that with HND's runway expansion, ANA's increase in slots at both NRT and HND and the (at last) arrival of the 787 at the end of the year (with ANA mainline pilots disappearing off onto that, leaving a mini-vacuum on the 767) and you've certainly got potential to see the continued requirement for AJV pilots.
I'm quietly confident (okay, not even that quietly) that things will continue as they are and AJV will keep recruiting. Sure, things are going to change a little with the combining of AJV/AJX but intially this will be mainly management personnel and will not affect the pilots too much. Eventually this will go the way our employers wish it to but, fingers crossed, the figures will have continued to go up and we'll all be happy bunnies again, just more efficient as a result of the recession.
