Specification against specification

Published figures. The better of the two on each measure is marked.

On Teterboro to West Palm Beach — 902 nm, a route both can fly — the Falcon 8X prices at about $32,500 and the Gulfstream G650ER at $35,500: a difference of $2,900 for the same trip. Estimates, not offers.

Where only one of them can go

Busy fields where one is excluded outright by published runway length or a wingspan limit. This decides more trips than any range figure.

Which one for your trip

A specification comparison answers which aircraft is better. It cannot answer which is available on your date, near your departure field, at a price worth paying — and that is usually what decides it. Ask, and a broker checks both with contracted operators.

Faster for same-day departures

Optional

A broker replies within 2 hours, 06:00–23:00 US Eastern. This opens a request, not a booking — nothing is confirmed until an operator returns a signed quote.
