The Bombardier Challenger 604 entered service in 1996 as a major evolution of the Challenger 601 series, introducing the more powerful General Electric CF34-3B engines (8,729 lbf each), an updated Rockwell Collins Pro Line 4 avionics suite with six-tube EFIS, and extended range of 4,077 nm.
The Challenger 604 puts usable space first, seating up to 10 in a cabin quiet enough for conversation, with a galley, a private lavatory and room to spread out on a long heavy jet charter flight. Cabin measuring 8 ft 2 in wide by 28 ft 3 in long, it is trimmed and insulated so engine noise fades into the background. Repeat clients tend to book this heavy jet again precisely because the hours on board feel like time gained, not lost.
With about 4077 nautical miles in hand the Challenger 604 turns a two-stop itinerary into a single hop, comfortably flying London to Dubai, nonstop and handing back the hours a fuel stop would cost. Crews plan a little under the book figure, since headwinds and a full cabin trim usable range, but on the sectors clients fly most this heavy jet reaches its destination without pause. On a heavy jet charter that reach is what buys back a whole half-day.
There is prestige in the Challenger 604 that goes beyond the badge: a Bombardier aircraft with a following among owners who could fly anything, a quiet marker of arrival for charter clients who notice such things. A large in-service fleet also keeps parts and expertise close at hand worldwide. Provenance like that is reassurance you can feel boarding it.
The Challenger 604 cruises around 459 knots near Mach 0.80, and on a busy heavy jet charter that pace routinely saves an hour or more against slower types, time returned at both ends of the day. High cruise also lets the crew climb above weather and airline traffic for a smoother ride. Speed is the one luxury nobody can refund once a day is spent, and it protects it.
Up front the Challenger 604 carries Rockwell Collins Pro Line 4 (six-tube EFIS, TCAS II, TAWS), whose situational awareness and automation translate into smoother, quieter, more precise flying for everyone in the cabin. Modern flight management also unlocks the steep, satellite-guided approaches that get the type into demanding airports. Good avionics rarely make the brochure, yet passengers feel them on every leg.
Here is the detail crews love: The Challenger 604 offers one of the widest cabins of any jet in its class, a direct legacy of the pioneering widebody Challenger that redefined business-jet comfort. It is the kind of heritage that quietly reassures a charter client.
Disadvantages of the Challenger 604 as a charter aircraft, and how we weigh them:
The Challenger 604 sits at the sharper end of its category on price, a reflection of its cabin, reputation and capability. Where budget is the single deciding factor a smaller or slightly older type can charter for less, and our advisors will say so plainly when it is the smarter call.
If outright top speed or the newest cabin technology is your single priority, a more recent design may edge it, yet for most travellers the Challenger 604 balance of comfort, capability and value is the more meaningful advantage on the day.
As alternatives to the Challenger 604, it is worth weighing the Challenger 605 and the Challenger 650, both able aircraft in the same bracket. Broadly the Challenger 605 carries the longer legs, while the Challenger 604 keeps the more modern flight deck, so the right pick comes down to your exact route, party and budget, which our advisors are glad to lay out side by side.
In short, few aircraft do long-haul and intercontinental charter as gracefully as the Challenger 604, and where it is the right tool we place it on fully vetted, certified partners at a fixed all-in price, with an answer back inside 30 minutes.
