Boeing has quietly updated the advertised range specifications for its entire 777X family on its official product pages, increasing maximum range for the 777-8, 777-9, and 777-8 Freighter without a formal press release [1][4][5]. The 777-8 now lists up to 9,500 nautical miles, a 755 nm increase from the previous 8,745 nm figure, while the 777-9 rises to 8,000 nm from 7,285 nm [1][4]. The 777-8 Freighter gains 590 nm, reaching 5,000 nm compared to the prior 4,410 nm [6][7]. Seating capacity shifted from fixed values to flexible ranges: 350–425 for the 777-8 and 375–450 for the 777-9 [3][6]. Web archives confirm the previous figures remained in place as recently as 17 June 2026 [1][10]. Boeing has not disclosed the technical basis for these marketing specification changes [6][10].
