The widest cabin in its class made the Challenger 600 series a three-decade franchise. The 605 is its refined middle age: reliable, roomy, and everywhere in charter fleets.
The Numbers That Matter
| Spec | Approximate Figure |
|---|---|
| Class | Heavy jet |
| Typical charter seating | 10 to 12 passengers |
| Range | about 4,000 nm |
| Cruise speed | about 470 knots |
| Cabin (length by width by height) | about 28.3 by 8.2 by 6.1 ft |
| Baggage | about 115 cu ft |
| Lavatory | Enclosed aft lavatory |
Figures are approximate manufacturer-class numbers for planning; individual aircraft vary by configuration, and your quote reflects the actual tail assigned.
Cabin, Seating, and the Bathroom Question
That 8.2-foot width is the whole pitch. Five hours to the coast feels like a den, not a tube, and the conference group seats four around a real table for working flights.
- Club four forward, four-place conference group center, three-place divan aft
- Ten to twelve passengers in a cabin more than eight feet wide
- The widest cross section in its class: two people pass in the aisle without the dance
Yes, an enclosed aft lavatory, and many tails add a forward crew lav so the main one stays yours on long legs.
A heavy jet cabin stops being seating and becomes rooms: a working zone forward, dining midship, a lounge aft that converts to beds, with a galley that produces actual dinner and a lav situation measured in doors rather than compromises. Cabin crews are standard, service is plated, and eight hours aboard leaves people reluctant to deplane. It is the class where the flight itself becomes part of the trip you paid for.
Baggage and What Fits
About 115 cubic feet plus generous in-cabin wardrobes. Group luggage, ski gear, event freight: the hold absorbs what ten people bring.
Models and Variants
Charter listings rarely say which generation you are getting unless you ask. The family tree, so the name on your quote means something:
| Variant | What changed |
|---|---|
| Challenger 604 | the 1996 long-range standard bearer |
| Challenger 605 | 2007 onward: bigger windows, new avionics and interior |
| Challenger 650 | 2015 to today: more thrust and the newest cabin |
The Trips It Was Built For

Flying It Out of Denver
The value door into heavy-jet charter from Denver: ten passengers, transcontinental or Hawaii-with-planning legs, and a cross-section that makes five hours feel civilized.
From Centennial, published range comfortably covers Las Vegas, Los Angeles, Chicago, New York, Miami.
Heavy iron out of KAPA flies the group missions and the long ones: twelve to the coast for the closing, London one-stop or nonstop by type, the multi-family spring break lift. The 10,001-foot main runway matters here; full-fuel, full-cabin departures on hot afternoons are exactly the case it was built for, and it is why heavy departures that would sweat elsewhere leave Centennial on schedule.
How Chartering One Works
Chartering this type through FlyCentennial works the same as every aircraft on the site: you send the trip through the Get Best Rate form below, we shop it quietly to operators flying this class out of the Front Range, empty legs get checked first, and one itemized number comes back with the tail, the year, and the interior spelled out. No membership, no deposit program, no phone tag with five sales desks. You compare, you ask questions, you book or you walk, and the quote costs nothing either way.
The Operator Behind the Tail
Every aircraft quoted here flies on a Part 135 air carrier certificate, which is the regulatory difference between commercial charter and a friend with an airplane: recurrent crew training, drug and alcohol programs, maintenance tracking, and FAA oversight on all of it. We match the trip to operators whose certificate, crews, and insurance fit the mission, and we will tell you plainly why a given tail earned the quote.
When to Book
On timing: a week ahead is comfortable for this class on domestic lanes, and two or three days is usually workable outside holiday crushes. The calendar spikes that actually bite are ski-season Fridays, major game weekends, and the days around Thanksgiving and Christmas, when the whole fleet is spoken for by noon. Book those the moment dates firm; everything else can breathe. Empty-leg matches, by nature, reward the flexible over the early.
What It Costs to Charter
Heavy jets carry the premium rates the cabins imply; on transcontinental and international legs the per-seat math with a full cabin gets surprisingly rational. Rates move with dates, positioning, and the specific aircraft, which is why we quote trips rather than publish a rate card that would be wrong by Friday. The form below returns a real number, free.
