Slick Airways had its original fleet of Curtiss C-46 Commando aircraft based at Lockheed Air Terminal (Burbank) and San Francisco Airport.
[3] In 1954, Slick Airways went into merger talks with Flying Tigers because of the increasing competition by passenger airlines, which failed because the respective shareholders would not approve of these plans.
[6] In October 1962 scheduled flights were resumed,[5] when Slick Airways was granted permanent permission to operate its transcontinental Route 101.
The trunk routing went from either San Francisco or Burbank to Dallas, St. Louis, Chicago, Indianapolis and New York City and was operated using the Lockheed Super Constellation.
Additionally, Slick Airways operated on so called Quicktrans domestic routes on behalf of the United States Navy.
