Northwest Airlines has added some 80$ in their roundtrip (US) domestic airfares as fuel surcharge.

Northwest Airlines Corp. confirmed on Thursday that it will add fuel surcharges of up to $80 for many domestic round-trip tickets.

The surcharge will apply to travel to about 7,000 city pairs beginning Jan. 10, Northwest spokeswoman Michelle Aguayo-Shannon said. She said Northwest is matching surcharges added by competitors in those markets. Northwest already has fuel surcharges in other markets, she said.
