In February 1991, ATA won a contract for daily 727-100 shuttle operations between Nellis Air Force Base and Tonopah Test Range in Nevada. This particular contract, formerly operated by defunct Key Airlines, was awarded to ATA and ended in late 1992 when Tonopah F-117 Stealth Fighter operations ceased. The 727-100s were replaced with Boeing 727-200s in 1993. Also in 1993, according to the Official Airline Guide (OAG), ATA was operating scheduled passenger service between New York JFK Airport and Lagos, Nigeria via a stop at Santa Maria Island in the Azores with a Lockheed L-1011 TriStar wide body jetliner.
