More credit card deals (cash, British Airways miles, etc.)

The crazy credit card deals continue, following the 100,000 points on Capital One (expired), 100,000 miles on American Airlines (technically expired, but still working), and 50,000 miles on Continental (valid till May).  Here are some current deals:

• British Airways: The deal for 100,000 miles on British Airways is back.  Sure, you get the whopping bonus (received after spending $2,500 on the card in 3 months) that you can redeem on American Airlines and avoid British Airway's high fuel surcharges.  But you also get a redeem-one-get-one-free offer for award travel (after spending $30,000 on the card), but you can end up flying first class to Europe for just your bonus miles plus fuel surcharges -- no way to avoid fuel charges on this one.
• Lufthansa: Barclays Bank offers the Lufthansa credit card with 50,000 Lufthansa miles, which is a Star Alliance airline (redeem on United, Continental, and US Airways).  But the miles do expire, and unlike most American programs, you can't extend their life by having activity on your account.  Yes, my Lufthansa miles expired on me and I am bitter. 
• $200 from Chase: If you don't like the idea of all these miles, you can also get some cold, hard cash back.  Chase offers $200 as a sign-up bonus for spending $1,500 in 3 months.
