Interesting thread. Can anyone add to the list of programmes that allow one-way awards?

Aeromexico (only for awards on AM)
Air Canada (only for awards on AC)
American Airlines AAdvantage (only via oneworld distance-based awards)
BA Executive Club
British Midland Diamond Club
Cathay Pacific Asia Miles
KLM Flying Dutchman
Mexicana (only for awards on MX)
United (unpublished perk for 1K flyers)

Thanks!
