British Airways Executive Club members will earn 30 percent bonus miles when transferring Marriott, Hilton or Hyatt hotel points into miles through Feb. 28, 2009. With the bonus, Marriott hotel points convert into miles at a ratio of 10,000 points for 2,600 miles (normally 2,000 miles), Hilton HHonors points convert into miles at a ratio of 10,000 points to 1,300 miles (normally 1,000 miles) and Hyatt Gold Passport points convert into miles at a ratio of 5,000 points into 2,600 miles (normally 2,000 miles). The offer is only available to members residing in the U.S., Canada or Bermuda. Be sure to transfer the points at least a month before you plan to use the miles because it is expected to take four to six weeks from the conversion date for your miles to post to your account.
