Beginning in 1998, Continental again embarked on a program to expand its international operations. It inaugurated services to Ireland and Scotland, and in October 1998 the airline received its first Boeing 777-200ER aircraft, allowing non-stop flights from Newark and Houston to Tokyo, Japan, and from Newark to Tel Aviv, Israel. Continental in the same year launched partnerships with Northwest Airlines, Copa Airlines, Avant Airlines, Transbrasil, and Cape Air, and Continental and America West Airlines became the first two US airlines to launch interline electronic ticketing. In 1999, Continental Airlines started service between Newark and Zurich, Switzerland, and from Cleveland to London.
