I've been saving up my miles and have enough for two first class tickets for my husband and myself to Sydney on Qantas. Are the FC awards difficult to get? I really want to treat my husband to FC rather than BC since I've been saving these miles a while and it will be our 10 year anniversary.

Any other airlines I should consider? I don't have quite enough miles for FC on Cathay Pacific and it looks like Delta and KE just have BC to Sydney.
