I travel quite a bit between the US and Saudi Arabia for work. Regrettably, I do not have the luxury of choosing my own itineraries. For years all of my work-related travel has been on Skyteam carriers and I've been crediting the miles to Delta Skymiles. However, my employer has now decided that we will be flying with Oneworld carriers and I am a loss as to which OW frequent flyer program to use. Some general info about my flying habits:

1) I appreciate Delta's operations & service so all my domestic flying will still be with DL.

2) I don't give a damn about credit card sign-up bonuses.

3) I care more for elite status then I do for earning redeemable miles; but, I have no idea which carrier will be getting the lion's share of my long-haul business.

4) Some travel may be on Emirates, which I can credit to JAL's program.

So does anyone have a favorite stand-out OW program.

Thanks!
