Doing the math, US with the 100% bonus is about $0.01/mile, which undermines the historic value of 1.5 cpm. I was tempted to get these miles for over the water business tickets, since US has done a lot of these trips in the past while for me while my half million and growing DL miles languish.
On a separate note, we FTs should support those that overpay. I willingly wait until the last day to see if I got upgraded for the overseas trip. Those that shell out thousands for their tickets for business or first is what keeps the airline going. I'm OK with the morsels in J that trickle down. Reading those testimonials in the thread about all the deals are amusing, since thru my FT experience, I had often taken the deal to even better values that the posters bragged about.
YMMV
