Our AQFO was an ALT guy and had never flown in Asia or been to Osaka (the three of us had been to Osaka numerous times plus had lots of Atlantic crossing experience). Nice guy and very knowledgeable of Delta procedures, but I think a whale FO instructor would have made more since if they were concerned about our first Pacific crossing. JMHO
Plus, when we told some LA guys about having Asia TOE they asked "what about us"? They hadn't been to NRT before either but didn't get anyone.
Don't get me wrong, I think the company being willing to spend money to make things go smoothly is great. But, I think they could have better used available experience.
