EXPERT VERDICT
The Gulfstream G150 is the stronger all-rounder, but the Gulfstream G100 (Astra SPX) still wins on the metrics that matter to specific buyers.
The Gulfstream G150 pulls ahead on range / non-stop reach, cabin comfort, group capacity, airport access and speed & block time. Both sit in the midsize 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
Gulfstream G150
3,000 nm of range — the better choice for transcontinental and intercontinental missions.
Cabin comfort
Gulfstream G150
Taller and/or wider cabin (5'9" × 5'9") — better for long flights and stand-up movement.
Group capacity
Gulfstream G150
Seats up to 8 — the right pick when the manifest grows.
Airport access
Gulfstream G150
Shorter 5,000 ft balanced-field requirement — opens up restricted alpine, island and city-adjacent airfields.
