About the Boeing 787-10 Dreamliner
Boeing delivered the first 787-10 to Singapore Airlines in March 2018. Boeing lists an overall length of 68.3 meters, compared with 62.8 meters for the 787-9 and 56.7 meters for the 787-8. Airlines can use the extra fuselage space for more rows or a different mix of cabin sections.
Seating capacity
Boeing lists 300–375 seats for a two-class 787-10. Singapore Airlines publishes a plan with 36 Business Class and 301 Economy seats, for a total of 337. ANA’s 429-seat domestic plan has 28 Premium Class and 401 Economy seats. These counts describe specific layouts. The operating airline’s seat map shows the arrangement for your flight.
Cabin layout
Many Economy rows on both published maps are 3–3–3, with three seats in each block and two aisles. ANA shows 2–2–2 in Premium rows 2 through 5. Singapore Airlines shows four seats across in its Business cabin, arranged 1–2–1 in full rows. If you prefer an aisle or window, check the row and seat letter together. The Singapore Airlines plan marks some positions without a window.
How to recognize a Boeing 787-10
Look for the long widebody fuselage and an engine beneath each wing. Boeing gives all three Dreamliner variants the same 60.1-meter wingspan, so the longer fuselage is a more useful clue in comparable side views. When perspective makes the proportions unclear, confirm the variant from the registration and model record.
