Be careful about Aegean redemption rates until some more clarity is provided, the charge "per segment" could make their rates quite expensive. I am in a similar position on BD (Feb 11 reassessment) and I am considering AC and OZ for the jump. TK could be problematic with a hard 3-year miles expiration rule.

If however, you choose Aegean, you will EASILY qualify *G so no worries there.
