One way awards at 50% of roundtrip pricing is so very important. I value BA, AA, BD miles so much higher because of this feature.

sbm12 said earlier that AA's one-way awards do not allow open jaws, which of course is not logical. A to B at 50%, C to A at 50% = 1 open-jaw award at 100%.

AA offers a free domestic segment for every international redemption for those of us living in international gateways. LHR-LAX-JFK - talk about bang for the buck!

One need not pay the full roundtrip pricing for one-way CO first class redemptions. For instance, you want LAX-FRA in LH F one-way. The LAX-FRA roundtrip F award price in 135,000 -- 50% would be 67,5000. You should book LAX-FRA in LH F and FRA-LAX in LH Y for 95,000 -- 70% of the roundtrip price. Not too bad.

Having the option for trip planning across so many carriers is just brilliant. BD miles for NH LAX-NRT-HKG with NRT stopover. Home HKG-LAX nonstop on CX in F via AA with a free one-way LAX-JFK in AA762 F anytime in the next year!

Miles for one-way LAX to SE Asia like KUL or CMB where you then buy a cheap cheap premium ticket back to North America.
