Throughout the bulk of 
Delta Air Lines’ past, its presence and growth ambitions were not situated in the Pacific Northwest. As a carrier with East Coast roots, many of Delta’s flights in the west only involved Los Angeles and Salt Lake City in the interior mountain West. However, as years went on and the airline and industry alike began to evolve, its network and fleet began to expand. After surviving a handful of setbacks – as with every other airline – Delta luckily powered through to become an industry leader.
