Which FF to put Czech (OK) miles into?
 

I have 1 return flight planned on OK.

Continental would be my first choice but seems that Czech V class does not earn any Onepass miles, right?

Is there any other US FF program to that would work? And preferably earn 100% miles?

says that both CO and DL give 100% miles for OK V class. I would double check current rules however.

That is definitely wrong. OK V fares earn nothing on CO.

It does still earn 100% on DL.

How far is the flight? If you're only going to get a couple thousand miles out of it and don't plan any more SkyTeam travel in the next 18 months the points are pretty worthless anyways.

why does it have to be a US-based programme?
Stick 'em into OK+. With the joining bonus (don't forget to PM me for a member-gets-member referral that'd give each of us 2000 miles :p ) , a couple of 500-mile surveys and some orphaned car rentals, you'll get to redeem them soon enough.

US based because:

1) Taxes are actually taxes, not YQ;
2) Europe is Europe, and not separated in 3 zones like in OK+;
3) Chance of flying OK again in the nearest 18 months – near 0%, flying DL or CO –.50%.
