Bombardier Challenger 604 Charter

The Bombardier Challenger 604 entered service in 1996 as the second-generation development of the widebody Challenger 601 — new General Electric CF34-3B engines, a redesigned wing with winglets, glass Collins Pro Line 4 avionics and 400 nm of extra range over its predecessor. Around 360 units were built between 1996 and 2006, when the 605 refresh took over. Bombardier built the 604 to be the workhorse of the transcontinental heavy-jet segment, and it succeeded: the type became the most widely operated wide-cabin heavy jet in North America and remains a fixture of major charter fleets two decades later.

The 604 is the aircraft that established the modern Challenger cabin — a genuine 8-foot-wide, 6-foot-tall stand-up cross-section that no super-midsize can match and no smaller heavy jet has been able to displace. Twenty-five years on, the 604's cabin still feels contemporary because the underlying dimensions were right from the start.

For charter clients the 604 is the value option in the wide-cabin heavy-jet class. It offers the same fuselage cross-section as the 605 and 650 at meaningfully lower hourly cost, with mature type support and broad fleet availability.

Cabin dimensions: 28 feet 3 inches long, 8 feet 2 inches wide and 6 feet 1 inch tall — genuinely wide, stand-up, flat-floor throughout. Standard layout is a nine-passenger double-club plus three-place divan; charter-common builds carry 10–12 seats with a forward crew rest and full galley. The seats are full-recline and tracking, and the divan berths into a genuine flat bed on transcontinental sectors.

Cabin management on original 604s is dated (Airshow / Rockwell Collins Cabin) but refurbished aircraft frequently feature updated Venue or Iridium systems, LED lighting and modern trim. Ka-band Wi-Fi is a common retrofit but not universal. Baggage volume is 115 cubic feet in an externally accessed heated hold.

The lavatory is fully enclosed with vanity, natural light through a dedicated window and belted seat. The galley is forward-right with hot and cold storage, oven and coffee — a real heavy-jet galley, not the compact installation typical of the super-midsize class.

Twin General Electric CF34-3B engines deliver 9,220 pounds of thrust each — jet-airliner-class powerplants with airliner-class reliability. Maximum operating Mach is 0.85; long-range cruise Mach 0.80. Certified ceiling is FL410. NBAA IFR range with eight passengers is 4,027 nautical miles — enough for New York to Paris (with reserves and favourable winds), Los Angeles to Honolulu, London to Dubai, or coast-to-coast US with material headwind margin.

Balanced field length at MTOW is 5,840 ft — long by super-midsize standards but adequate for essentially every business airport that matters. Landing distance is 2,880 ft. The 604 is not a short-field aircraft; steep-approach and mountain-airport operations require careful weight planning.

Fuel burn is competitive at 340 gph in cruise — higher than modern peers per hour but lower per seat given the cabin capacity.

Charter hourly rates run $6,800–$8,500 in North America; €7,500–€9,000 in Europe — meaningfully below the 605 and 650. Empty-leg availability is broad because the fleet is large. Indicative pricing: New York to Paris from $60,000; London to Dubai from £52,000; Aspen to New York from $34,000; Miami to São Paulo from $58,000.

Against the 605 the 604 gives up modern avionics and cabin management at 15–20 per cent lower cost with the same performance envelope. Against the G450 the 604 offers a wider cabin at 20–30 per cent lower cost and gives up 250 nm of range. Against the Falcon 2000LX the 604 wins on cabin volume, loses on runway performance and fuel burn.

The commercial case for the 604 is straightforward: eight-passenger transatlantic capability with a wide heavy-jet cabin at charter rates 20–30 per cent below newer peers.

Charter the 604 when the mission demands a wide heavy-jet cabin for eight to twelve passengers on a transcontinental or transatlantic sector and budget matters. Refurbished aircraft with modern cabin management deliver a strong experience at charter rates well below the newer Challenger and Gulfstream heavy alternatives.

Prefer the 605 for the same airframe with a modern cabin, or the G450 for Gulfstream service network and additional range. For value-conscious wide-cabin heavy-jet charter, the 604 remains one of the most rational choices on the market.
