Northwest, Delta, Continental and US Airways followed United Airlines' February move in charging $25 for checking a second bag. Delta announced recently it would charge $3 for each bag checked at the curb, The Washington Post reported.
Northwest recently raised the fuel surcharge from $140 to $160 for one-way international flights, the report said.
