The Cessna Citation Longitude and the Citation X are Textron Aviation's two best-known super-midsize jets. The Longitude is the newer, wider cabin. The Citation X is the speed record holder. This guide compares them using Textron's own published specifications for the Longitude and for the Citation X+, the final version of the Citation X.

Speed: the Citation X wins
Textron calls the Citation X+ the fastest civilian aircraft in the sky, with a top speed of Mach 0.935 and a maximum altitude of 51,000 ft. The Longitude lists a maximum cruise speed of 483 ktas and a top speed of Mach 0.84. On long trips such as coast to coast, the X can save time in the air. On short hops, the difference is small.
Cabin: the Longitude wins
Both cabins are 25 ft 2 in long, but the Longitude is 4 in taller and 11 in wider, with a flat floor and a 6-ft stand-up cabin. Textron says the Longitude has the quietest cabin and the most legroom in its class, and its baggage compartment can be reached in flight. The Citation X+ cabin has 13 large windows, wide reclining seats and a belted lavatory. For groups who want to stand, walk around or sleep, the Longitude is the more comfortable choice. For a more detailed look inside, see our Cessna Citation X interior guide.
Range and runways
The two jets list similar maximum ranges: 3,500 nm for the Longitude and 3,460 nm for the X+. In practice, passengers, baggage, winds and reserves decide whether a trip is nonstop. The Longitude needs less runway, 4,810 ft versus 5,250 ft for the X+ at maximum takeoff weight, which can matter at shorter or high-elevation airports. Your operator runs the performance numbers for each trip. See our Citation X range guide for more.
Availability
Textron ended Citation X+ production in 2018 and named the Citation Longitude as its super-midsize jet going forward. The Longitude is still in production. Both aircraft fly with charter operators, and many Citation X aircraft in service are earlier versions with different specifications than the X+.
Which should you charter?
- Choose the Citation Longitude if cabin comfort matters most: a wider, taller, flat-floor cabin, the most legroom in its class and a quiet ride.
