A major Port Columbus airline's decision to close its operations may mean longer flights for area passengers. America West Airlines, the nation's largest low fare airline, announced that it is eliminating hub operations in Columbus, Ohio, and, as a result, phasing 12 regional jets out of the America West Express Fleet. Between early April and mid-June, America West will gradually downsize the hub from 49 non-stop flights to a planned 4. For some passengers this basically means longer flight times amd getting connecting flights to reach their final destination. For passengers who will be affected by the change, and have already purchased tickets, and will be traveling on or after April 1st, will be contacted by their travel agent or American West Airlines.
