Horizon Air, a subsidiary of Alaska Airlines canceled more than 100 flights Wednesday after aircraft manufacturer Bombardier advised airlines to ground some Q400-model turboprops (pictured left). According to the Associated Press, some cities that had Horizon flights canceled included: Spokane, Bellingham and Pasco, Wash.; Portland and Eugene, Ore.; Boise and Idaho Falls, Idaho; Billings, Bozeman and Kalispell, Mont.; Vancouver and Victoria, British Columbia, and Edmonton and Calgary, Alberta.
An airline spokesperson said that the aircraft may be out of service for several days while they investigate landing gear problems that occurred on similar model planes in Europe. Alaska Airlines has substituted some of their planes into service temporarily in some effected Horizon markets.
