How this map was built

Singapore Airlines' current fleet page lists the 253-seat Long Haul configuration and links the official map transcribed here. Business is 42 seats: rows 11, 12 and 14-17 full at 1-2-1 (24), row 18 centre-only (2), and rows 19-22 full (16), for 42. Premium Economy is rows 31-33 full at 2-4-2 (24); the map colours only 31A/31C/31H/31K as Extra Legroom, but they remain Premium Economy tier W because they retain the Premium Economy product. Economy is 187 seats: rows 41-45 full (45), partial row 46 with six outboard seats, partial row 47 with seven seats, rows 48-61 full (126), and partial row 62 with three centre seats (45 + 6 + 7 + 126 + 3 = 187). Six Economy positions are coloured Extra Legroom (47B/47C/47H/47J and 48A/48K), so the computed SeatRecon summary is 42J/24W/6N/181Y while SIA's marketing count remains 42J/24W/187Y. Forward Zone is rows 41-46. The PDF legend includes a Windowless symbol but does not place that symbol on any seat; no no_window claim is made. All window positions remain unknown because the schematic is not to scale and there is no A350 engineering window grid in the repository. The announced retrofit successor is recorded but not generated without a published current successor map.
