Northwest Airlines announced on Tuesday that it will no longer charge elite-level frequent-fliers $15 to secure some of its aisle and exit-row seats. Northwest in March first began charging fliers $15 for certain aisle and exit-row seats, which can have up to 10 extra inches of legroom, as part of its "Coach Choice" program, the Detroit Free Press reports. Customers can reserve one of those “choice” seats within 24 hours of departure when they check in for their flights -- a move that Northwest estimates will bring in as much as $15 million in extra revenue. But now, Northwest’s elite-level fliers –- those who fly 25,000 miles or more in a year –- can reserve the choice seats within 24 hours of their flight at no charge. Previously, Northwest charged elite members the $15 fee, but gave them 36 hours instead of the standard 24 to buy them.
