American quietly relaunches Miami-Seattle as high costs force Alaska to Fort Lauderdale

American Airlines has opted to quietly backfill flights from Miami to Seattle being abandoned by Alaska Airlines, which has chosen to transfer flights to lower-cost Fort Lauderdale International Airport. It appears American believes it can capitalise on its dominant carrier status at Miami to operate flights to Seattle profitably.

The new flights were rolled softly, placed on a list of new routes featured on American's website and loaded into its schedules. American opted not to unveil the routes through a normal announcement.
