EXPERT VERDICT
The Challenger 650 pulls ahead on cabin comfort; the G450 answers with range / non-stop reach, group capacity, airport access and speed & block time. Both sit in the heavy jet class, so charter pricing is broadly aligned — let the use case (range, group size, airport pair) drive the final call.
Range / non-stop reach
G450
4,350 nm of range — the better choice for transcontinental and intercontinental missions.
Cabin comfort
Challenger 650
Taller and/or wider cabin (6'1" × 8'2") — better for long flights and stand-up movement.
Group capacity
G450
Seats up to 14 — the right pick when the manifest grows.
Airport access
G450
Shorter 5,600 ft balanced-field requirement — opens up restricted alpine, island and city-adjacent airfields.
Speed & block time
G450
Cruise of Mach 0.88 — shaves meaningful minutes off every long leg.

| ROUTE | DISTANCE | RECOMMENDED | WHY |
|---|---|---|---|
| London → New York | 3,000 nm | Either | Both aircraft fly this comfortably non-stop — choose on cabin and price. |
| Paris → Dubai | 2,950 nm | Either | Both aircraft fly this comfortably non-stop — choose on cabin and price. |
| Miami → São Paulo | 3,500 nm | Either | Both aircraft fly this comfortably non-stop — choose on cabin and price. |
| Hong Kong → Sydney | 3,950 nm | G450 | Only one reaches non-stop — the other would need a fuel stop (3950 nm > 4,000 nm). |
