Northwest Airlines is adding service fees on award tickets redeemed on or after Sept. 15, 2008. Similar to the fuel surcharge award ticket fees that Delta has introduced, members of Northwest WorldPerks will have to shell out between $25-100 for award tickets. WorldPerks will charge $25 for domestic tickets, $50 for transatlantic tickets and $100 for transpacific tickets; compare this to Delta’s fees of $25 for domestic and $50 for all international destinations. About the new fee, Doug Steenland, President and CEO of Northwest Airlines said, “This is a temporary service fee to partially offset our fuel costs. As fuel comes down, we will re-visit this decision.” All members, including elite members, will be required to pay the service fee, which is described as a fuel surcharge on the WorldPerks Award Travel Fees chart.

Northwest is also asking a $15 fee for a first checked bag, matching the new baggage policies of American Airlines, United Airlines and US Airways. The new fee applies to tickets sold on or after July 10, 2008 for travel beginning Aug. 28, 2008 on flights within the U.S. and between the U.S. and Canada. NWA also charges $25 for a second checked bag and $100 for three or more checked bags. Elite members and full-fare coach passengers are exempt from the baggage fees.

Northwest is also raising its call center fees. The call center ticketing fee is now $25 (up from $15) and the call center assistance fee for award travel is $20. Platinum and Gold elite members are exempt from call center ticketing fees.

And if you make any changes to your ticket, as of July 9, 2008, the fee for domestic non-refundable ticket changes increased from $100 to $150 and international ticket change fees increased by $50 to $150 per ticket, depending on class of service and other restrictions.
