Merrill+ is 25000miles per $500 cost of the ticket - meaning a $501 ticket costs you 50k miles, but a $499 ticket (even international, I believe) costs 25k. Similar restriction to the chase card, but slightly more flexable. This is only on their prefered carriers (BA, AA, CO, DL) but that covers enough for me (non-prefered carriers for 30k). I also like this because a trip to Europe on BA means I can often get BA World Traveler Plus (Economy+) tickets for the same 50k points it would cost me for standard Economy tickets on other cards (assuming it doesn't go over $1k), makes me not feel like I'm getting ripped off on 50k points flying out of BOS when ot costs the same out of LAX. You can also transfer miles to BA in 5k increments. Free Admirals Club or Crown Room membership when you spend $50k+/yr. Plus (the real reason I have this card) 0% foreign transaction fee, and 24/7 domestic call centers (not sure how long that will last).
Edit: Aparentally they do transfer bonus's as well - right now BA transfer is 5k M+=6k BA. That's almost as good as the SPG bonus (too bad its only to BA, and the promo ends Aug 31st).

I'd stick with a TY card though.

There's always Amex Starwood, but it has a $30 annual fee unlike all the other options that have been presented so far.
