Northwest Airlines Tries Another Fare Increase

Northwest Airlines Corp. said that high fuel prices are prompting it to try another fare increase.

Northwest said it added $50 each way to fares that had been capped at $499, and added $5 each way to fares that match discount carriers. It said it was adding a two-night minimum stay in some markets. An employee hotline message said the increases went into effect Tuesday.

This is the second time Northwest has added $50 to fares that match the $499 cap Delta Air Lines Inc. introduced in January. The last one failed after other carriers wouldn’t match it.
