EXPERT VERDICT
The Falcon 6X pulls ahead on cabin comfort and airport access; the G550 answers with range / non-stop reach and speed & block time. Both sit in the ultra long range class, so charter pricing is broadly aligned — let the use case (range, group size, airport pair) drive the final call.
Range / non-stop reach
G550
6,750 nm of range — the better choice for transcontinental and intercontinental missions.
Cabin comfort
Falcon 6X
Taller and/or wider cabin (6'6" × 8'6") — better for long flights and stand-up movement.
Group capacity
Even
Matched specifications.
Airport access
Falcon 6X
Shorter 5,480 ft balanced-field requirement — opens up restricted alpine, island and city-adjacent airfields.
Speed & block time
G550
Cruise of Mach 0.89 — shaves meaningful minutes off every long leg.

| ROUTE | DISTANCE | RECOMMENDED | WHY |
|---|---|---|---|
| London → Singapore | 5,900 nm | G550 | Only one reaches non-stop — the other would need a fuel stop (5900 nm > 5,500 nm). |
| New York → Tokyo | 5,850 nm | G550 | Only one reaches non-stop — the other would need a fuel stop (5850 nm > 5,500 nm). |
| Dubai → Los Angeles | 7,250 nm | Either | Both would require a tech stop on this routing — talk to us about positioning. |
| Hong Kong → New York | 7,000 nm | Either | Both would require a tech stop on this routing — talk to us about positioning. |
