Thanks for flyertalk forum, I found out this amazing deal. You can Fly ANA First Class for 60000 Aegean Miles. You can find it only on this routing working both ways LAX-HND-LHR-FRA. It’s 2 flights over 12 hours, business class is 45000 Miles, economy 30000 Miles.
If You start in London You have to pay ADP tax so it’s more expensive (Taxes for economy is 385 Euro).
You can also find Asiana First class on routing FRA-ICN-LAX.
Aegean Miles+Bonus is my main star alliance program, because its easy to get Gold card with them and keep it. You can buy up to 50000 Miles with them per membership year, sometime they have also bonus 40-50%, but last November they had 100% bonus, so You could buy 60000 Miles for only 750 Euro and with taxes in theory is possible to book this deal under 1000 Euro.
Aegean Miles+Bonus allow search redemption only if You have enough milers in Your account.
