Update #4: this offer is supposed to expire sometime on Tuesday 7/17. The best credit card mileage deal from last year is here again. Sign up for a British Airways Visa Signature Card to get 50,000 BA Miles (they're called Avios) after your first purchase, enough for a round-trip economy ticket to Europe. Even better, spend $10k and you'll earn 25k more or spend $20k and you'll earn 50k more. After signing up and spending $20k, you'll have 125k miles after the bonuses and the standard 1.25 miles per dollar spent. Then, for example, you can redeem 80k miles for a business class flight from the East Coast to Europe. There's a $95 annual fee. BA adds high surcharges to their flights, but you can use their miles on partners like American Airlines or Cathay Pacific.
