BA's a fortune from LAX in WT+ but out of JFK they're MUCH cheaper, $2350 all in. Transcons can be had for $350 or even less so... If you have the budget, that's what to do. Alternatively, what about LH via FRA? Can you upgrade on them? $1600 in May. I just hate to see you stuck in the VERY back for that long. I suppose you can hope for an op-up.
