Muse Air and successor TranStar Airlines served McAllen in the mid 1980s. In 1985, Houston-based Muse Air was sending up to five departures a day non-stop to its hub at Houston Hobby Airport with McDonnell Douglas DC-9-50s, all continuing direct to Dallas Love Field. Muse Air was acquired by Southwest Airlines which changed the Muse Air name to TranStar, and continued independently with nonstop DC-9-50s to Houston Hobby and one-stop to Dallas Love Field. TranStar went out of business in 1987.
