Status credits on frequent flyer points bookings

Do I earn status credits for flights bought with frequent flyer points?

Do I earn status credits for flights bought for other people?

Do I earn status credits for flight bought for other people with my frequent flyer points?

Thanks

No for all questions

(1)For Virgin Australia flights, it depends on the fare class of your redeemed ticket:

You can book a "saver" or "flexi" or even business class seat fully by using your velocity points, but it is much much more expensive than a "reward" or a "reward business" seat, which, on the other hand, entitles you nether status credits nor millages. A reward flight is also not counted as a "eligible section" for upgrading or maintaining your membership tier.  

(2) Virgin Australia has a "family pooling" option, by which you can give your points to another velocity member living at the same address. One can receive status credits and mileages from at most one adult and four minors. Note: you cannot give "eligible sections" to a family member. He or she must fly at least 4 sections that has a VA flight number for a gold tier and so on. 

(3) I'm not sure if you can buy a ticket for your friends by using your name -- you don't need to show your ID when checking-in a domestic flight nor bording. By doing so, you can certainly enter your flyer number and gain the credits and sections even you are not the one who is flying. I don't think it is right, but it would be practically possible.

(4) You can book flights for anyone (even for a non-member) by using your velocity mileage. I'm not sure how it goes with other airlines.

And it is illegal to use a fake name for booking a flight -- DO NOT do it.

Apart from Any Seat Awards (which will earn points and SCs) -- albeit these are usually so expensive that most won't use them.
