Well if you can't beat 'em, join 'em (pun intended)*....
Damn well hard to walk away from such a promotion, and with good redemption rates.... might set up two accounts so can redeem tix for two people (although can I shoulder $2,600++ is another thing; might just buy for myself...)
Anyone find the routing rules for US? From what I can see, there are some restrictions (e.g. between Europe and Asia/South Pacific, cannot travel via Americas), and choice of either open jaw or stopover (but not both, and only one stopover overall if you choose it) (I wonder if you can have the open jaw at the destination side rather than the origin side, e.g. SYD-BKK-ZRH // LHR-ICN-SYD, with no stops at BKK or ICN).
BD is still OK because of cash+miles makes some awards low and accessible, as well as one-way awards, but much, much higher cash components (both fuel surcharges and miles+cash cash component), not to mention it seems you can almost take US for a ride on routing as long as you don't exceed 23h 59min at any certain location (within some reason), whereas BD is clamping down on such round-about routings and charging more for indirects and even some select "only choice" routings (e.g. an itinerary going to KTM).
I don't know how US keep doing this (although making miles from sales is something), plus it puts quite a bit of pressure on the *A burning arena. I'm sure that my first US award is going to garner some annoyed faces from the other *A partners at check-in!
* Yes this is a concession on an earlier position
