The story
Boeing stretched the 777 one more time, gave it carbon wings as wide as a 747's, and then hinged the last eleven feet of each so it still fits a 777 gate. Under those wings hangs the GE9X, the biggest and most powerful commercial jet engine ever built, each one as wide as a 737's fuselage. The first one flew in January 2020 and the type has lived in certification flight test ever since: seven had flown by mid-2026, thirty more sat built and waiting at Everett, and no airline had taken delivery. A 777-9 on your map is almost always wearing a Boeing test callsign.
The original 777 was offered with folding wingtips in the 1990s and nobody bought them. The 777-9 is the first airliner actually built and flown with them: about 11 ft of each wing swings up after landing so a 235-foot span can park at a gate built for 213.
