China Eastern Airlines COMAC C919 seat map

ONE CURRENT CONFIGURATION FOUND. Wikipedia's China Eastern fleet table, current to May 2026, lists 16 C919-100STD aircraft and only one passenger configuration: 8 Business / 156 Economy = 164. COMAC's first-delivery release independently publishes the same two-class split, and COMAC's May 2023 Jetliner magazine repeats it for the aircraft's entry into commercial service. PUBLISHED CABIN FACTS: Economy is 3-3; its middle seat is 1.5 cm wider than the adjacent seats. Business uses a cradle recliner that reaches 120 degrees with pitch exceeding 1 m, with a privacy divider near head level between paired seats. The cabin has twenty 12-inch overhead displays supporting 1080p programming. DERIVED_FROM_COUNTS: no China Eastern or COMAC LOPA, seat-number chart, or row-position plan was found. Business is reconstructed as two 2-2 rows (2 rows x 4 = 8) using standard narrowbody A/C-D/F lettering; the paired-seat description supports 2-2 but does not publish row numbers. Economy is reconstructed as twenty-six 3-3 rows (26 x 6 = 156), numbered sequentially 3-28. Every cabin and row is marked derived. Door/exit, galley, lavatory, wing, bulkhead, and cabin-divider positions are omitted rather than fabricated. Window alignment is unknown for window-position seats because no C919 engineering window grid or published map is available; interior seats use no_window_seat. No absolute seat width or Economy pitch is asserted.
