As the summer travel season takes off, pilots at Northwest Airlines are warning fliers to brace for a barrage of flight cancellations like those that occurred the past weekend.

Northwest Airlines canceled between 240 and 452 flights across the country because the carrier did not have enough pilots available, a spokesman for the airline's pilot association said Monday.
