From the 1960s to about 1985, Trans World Airlines had a small hub at Pittsburgh. It began direct transatlantic flights in May 1981, to London Heathrow via PHL and nonstop to Gatwick. Neither lasted long; the next transatlantic nonstop may have been USAir's 767 to Frankfurt about 1990. The nonstop Frankfurt service was revived by foreign carrier Condor in 2017 but was terminated in 2020 due to the COVID-19 pandemic. The flight was flown two times a week using a Boeing 767-300ER aircraft.
