EVA Air Boeing 777-300ER seat map — 353 seats

EVA Air's current English 777-300ER selector publishes this 77B map alongside 77M, 77A and 77B and gives exact class counts and pitch. 77B arithmetic: Royal Laurel rows 1-3 and 5-6 are full 1-2-1 (20), row 7 has D/G/K (3), and rows 8-11 are full (16), totaling 39. Premium Economy is seven full 2-4-2 rows 20-26 (56). The denser Economy cabin is published 3-4-3: rows 45-57 are full (130); the rear section has the six side exit seats at row 60, nine full rows 61-69, tapered 2-4-2 rows 70-72, and tapered row 73 with A/C, D/E/F/G and H/K (128), totaling 258. Every enumerated row, seat letter, cabin break, door and modeled monument is transcribed from EVA Air's official raster. The map highlights the six side seats at rows 45 and 60 as exit seats; these receive the physical extra-legroom flag but remain Economy (Y), because EVA does not publish them as a separate branded cabin. The map's gray-filled aft-center block is modeled as non-reclining seats, while the white side pairs remain ordinary seats adjacent to the rear lavatories. EVA explicitly identifies 21A/K, 24A/K, 45A/K and 60A/K as no-window-view seats; only those get evidence-backed windowAlignment none. Every other window-position seat remains unknown because the top-down map does not prove alignment to the real window grid. The wing band follows the outline drawn from rows 23 through 52. No hardware manufacturer, seat width, screen size, or per-configuration fleet count is asserted.
