Perfect storm of signup bonuses

I was writing this post yesterday but my blogging software wasn't behaving, and Mommy Points beat me to the punch! Go read that post, but here's the quick and dirty: there are a number of too-good-to-miss signup bonuses available right now, so if you've been waiting for the right moment for a credit card application cycle, this is the right moment. Here are the cards I would apply for today (no affiliate links here, obviously):

• Bank of America Alaska Airlines Visa Signature, 50,000 miles after $1,000 in spending. Arguably the most valuable traditional airline miles, and inarguably the highest offer ever made for this credit card. This is the time to get it.
• Barclaycard Lufthansa Miles & More World MasterCard, 50,000 miles after $5,000 in spending.
• Chase British Airways Visa Signature, 100,000 miles after $20,000 in spending within the first year. A high spending requirement, but also the highest this offer has ever been. After spending $20,000 on the card, you'll have earned 125,000 Avios, or 6.25 Avios per dollar (the card earns 1.25 Avios per dollar on non-bonused spending).
• Citi Platinum Select / (American Airlines) AAdvantage World MasterCard, 50,000 miles after $3,000 in spending.

These are all best-in-class offers, and it's vanishingly unlikely that they'll all be simultaneously available again in the near future. If you wanted to add an American Express card into the mix I'd probably go for a Starwood Preferred Guest personal or business card, unless you're in the hunt for Delta Platinum or Diamond status, in which case you could apply for a personal or business Delta Platinum American Express. I'm not thrilled with any of the Membership Rewards signup bonuses currently available, unless one of my readers can point to something better than the 25,000 point signup bonus for the Premier Rewards Gold card.
