This is N806PA at Berlin-Tegel ( TXL ), ca. 1987. Flights operated mixed domestic/international services,
i.e. TXL-HAM-JFK, they also were workhorses on the TXL-FRA route, I am not sure about international
connections. These years were very confusing, United and TWA were operating B 727īs into London,
then widebodies to the U.S.. All under the same flight number.
