Alaska Airlines has been a staple on the West Coast for its more than 90-year history. However, in the last two decades, the carrier has been able to expand its route network to several destinations throughout the Midwest, South, and East Coast. Similar to its Hawaii network, the airline spent several years building its operation throughout the continental US, thanks to growing its Boeing 737 fleet. With Hawaiian Airlines now as its sister airline, the sky seems to be the limit, in terms of its overall footprint and position as a major competitor.
