Not yet: 0 of 71. None of United's 71 A320s has Starlink yet (68 checked on united.com, 3 not yet). As of Nov 6, 2026.
United's stated target (Oct 3, 2026): more than 880 aircraft with Starlink by the end of 2026, and the whole fleet by the end of 2027.
Flights that usually get an A320, so expect Panasonic Wi-Fi rather than Starlink.
