When he flies transatlantic on, say LH, A3 *G will bring him exactly the same benefits as flying it with US air's *G status.
And if he holds A3 *G, he will (even if using his US program to collect the miles on this flight) have lounge access when flying domestic, by simple presenting his card. Status is valid for 3 years without any further miles into the program, and it's super quick to get, for full *G advantages. Sure, having AFTERWARDS a go at a US-carrier *G status will be my idea as well, but making A3 *G first won't be bad. Quicker *G benefits, lounge access for domestic flights within the US (as well as in Europe.. when he gets no lounge in Paris AND FRA/ZRH for quite a while till he gets US *G, it will hurt him quite a bit!), in my eyes certainly not too bad.
But it's to everyone's own liking, of course

Of course. My suggestion of US was based on a couple assumptions:
1)The OP cares about price ex-BOS (judging by their comments on EI and B6)
2)The OP is willing to fly US TATL (and US is often cheapest, and if not, usually very competitive)
3)The OP cares about RDM accumulation and redemption
Also, all the suggestions of A3 have a massive catch - many people are abusing their status by changing their program at the gate so it credits to a different program instead. If this keeps up, A3 will have no choice but to raise the tier levels.
