The OP's info lists *wood as his hotel program, but Hilton currently gives 1000 BMI miles for every night stayed at ALL of their properties. This is huge compared to 500 miles PER STAY (regardless of # of nights) for most other airlines... and that drops to 100 miles PER STAY for Hampton Inns and Homewood Suites. I'm based in the US, my main airline program is Delta Skymiles (SkyTeam), and I haven't been to the UK in about 4 years, but all of my Hilton Double-Dip miles go to BMI for use elsewhere in *A... and my Hilton stays earn anywhere from 2x - 30x* what I would earn if I credited them to Delta or most other airline programs. 60 nights a year at Hilton properties = enough for 2 *A USA domestic coach round trips, 1 *A USA domestic business round trip, or 1 *A international coach round trip.

* 1 night Hilton = 500 Skymiles or 1000 BMI miles = 2x
* 3 night Hampton = 100 Skymiles or 3000 BMI miles = 30x
