I'd like to get to Spain towards the new year and looking for a good redemption. Cheapest flight I found was $500 on aerosnot, I can do better.

I've access to UA (50k), AA(20k), Lufthansa(20-30k eventually), and either Alitalia or Flying Blue (will earn more with AZ but FB has those promo awards). I am out of the US and likely no opportunities to get new cards or MS.

I will go to the US or similar W hemisphere place after Europe.

What's the best scenario? To me either Lufthansa 30k from India or a promo award looks best, but wondering if I'm missing something. Would much prefer to leave from SEA than India/S Asia.
