 Portland Maine's Portland International Jetport was recently expanded, providing the state with increased air traffic from carriers such as JetBlue and Southwest Airlines.Maine has very few large companies that maintain headquarters in the state, and that number has fallen due to consolidations and mergers, particularly in the pulp and paper industry.Some of the larger companies that do maintain headquarters in Maine include Fairchild Semiconductor in South Portland; IDEXX Laboratories, in Westbrook; Hannaford Bros. Co. in Scarborough; TD Bank in Portland; L.L.Bean in Freeport; and Cole Haan in Yarmouth.
