Sơ đồ chỗ ngồi Bangkok Airways ATR 72-600

CURRENT OFFICIAL CONFIG: Bangkok Airways' public booking engine assigns ATR configuration PM4 to future PG307 and publishes 70 Economy seats in a 2-2 high-wing turboprop cabin. There are 18 physical seat rows across display numbers 1-12 and 14-19: rows 1-12 and 14-18 are full A/B-C/D rows, row 13 is omitted, and final row 19 contains only 19A/19B because the galley occupies 19C/19D. This exact published layout differs from the corpus's Citilink ATR arrangement, which has its partial row at the front. Row 1 is the exit/leg-space row; 18C/18D and 19A/19B carry the restricted-recline characteristic. A rear lavatory sits after row 19. SeatLink resolves the map to 4N/66Y. No ATR window grid exists, so windowGridType is omitted. The pre-existing narrow atr72600 registry entry already covers exactly 70 seats and max display row 19, so no duplicate atr72 registry key is created. Availability states are ignored.
