The leg

Key West to Cancun

The great circle track from Key West to Cancun runs 353 nautical miles on an initial heading of 234 degrees true. A very light jet covers it nonstop in roughly 1h 15m, before winds.

At this length the aircraft reaches a settled cruise and the class differences start to show up on the clock, though not dramatically. The bigger separation is cabin comfort and baggage volume. The clock change is no clock change in winter and 1 hour behind in summer, because the two cities shift their daylight saving rules on different dates.

You do not need a large cabin for the distance. A Embraer Phenom 100EV in the very light jet class covers it nonstop with margin left over.

Book range figures assume long range cruise, standard reserves and a stated payload. Load the cabin, add bags, put the departure field at elevation on a hot afternoon, and the real number comes down. We treat anything above roughly 80 percent of book range as a leg that needs the operator to confirm against the specific tail number rather than the brochure.

Airports

Which runway you actually use

Departing Key West. Most charter traffic uses Key West International (KEYW / EYW). The credible alternates are Florida Keys Marathon (MTH). Which one you leave from is worth deciding on ground time rather than on the map, because twenty minutes of extra driving often buys a cheaper ramp and a faster departure.

Key West has a short runway by jet standards and ramp space is tight during winter season.

Arriving Cancun. Most charter traffic uses Cancun International (MMUN / CUN). The credible alternates are Cozumel International (CZM). Pick the one closest to where you are actually going. The airport with the famous name is frequently the wrong answer.

Runway length, ramp space and operating hours at the arrival field decide the aircraft as often as range does. Have the operator confirm all three against the tail number they are offering.

Airport	ICAO	IATA	Metro	End	Role
Key West International	KEYW	EYW	Key West	Departure	Preferred
Florida Keys Marathon	KMTH	MTH	Key West	Departure	Alternate
Cancun International	MMUN	CUN	Cancun	Arrival	Preferred

Cost

What moves the number

We do not publish a price for this route, and neither should anyone else. Here is what the number is actually made of.

Positioning. Where the aircraft sits when you call. If it is already on your departure ramp you pay for your legs only. If it has to fly in empty and fly home afterwards, someone pays for that, and it is you.
Daily minimum. Most operators bill a minimum number of flight hours per day the aircraft is away. A short leg with a three night stay can price higher than a long leg that returns the same day.
Crew duty. A crew has a legal duty limit. Cross enough time zones or depart late enough and the trip needs a second crew or an overnight, and both cost money.
Ramp and handling. Landing fees, ramp fees, overnight parking and the FBO handling charge vary enormously between fields in the same metro.
Peak days. Operators apply surcharges around the predictable weekends. Thanksgiving Sunday, the Super Bowl, Art Basel, the Fourth of July and the ski season change of week all price differently.
International handling. Customs, immigration, overflight permits, landing permits and a local handling agent. On some routings the permits need days of lead time.

Our fee sits on top of the operator price as its own line, visible, so you can see both halves. Send the trip and the operators bid against each other on all of the above at once.

Timing

Season, weather and the clock

Cancun sits in the tropics, where the practical seasons are wet and dry rather than hot and cold. Afternoon convective weather is the routine cause of delay, so morning departures hold their schedule more reliably.

Questions

EYW to CUN

How long is a private jet flight from Key West to Cancun?

The great circle distance is 353 nautical miles, which is about 654 km. A very light jet covers it nonstop in roughly 1h 15m block to block. A heavy jet flies the distance in about 1h 06m, and a light jet in about 1h 08m if it can make it without stopping. These are planning estimates in still air and exclude winds and air traffic routing.

Can a light jet fly Key West to Cancun nonstop?

Yes. A Embraer Phenom 300E covers this leg nonstop with comfortable margin, using about 18 percent of its published range. That is inside the band where a full cabin and average winds will not force a stop.

Which airport should I use in Cancun?

Cancun International (MMUN) handles most charter traffic. The alternates are Cozumel International (CZM). Choose on ground time to your final address rather than on the name you recognise.

Do I clear customs on a private flight from Key West to Cancun?

Yes. Crossing a border on a private aircraft still means customs and immigration at both ends, but it happens at the private terminal rather than in a terminal queue, and it is usually a matter of minutes. The operator files the passenger manifest in advance, so passport details are needed before departure rather than at the airport. Some routings also need landing or overflight permits with days of lead time, which is worth raising early.

What does a private jet from Key West to Cancun cost?

We do not publish a figure, because a fixed number for this route would be invented. The dominant variable is where the aircraft is parked when you call, not the aircraft type. Positioning legs, daily minimums, crew duty, ramp fees, peak day surcharges and taxes all move the total. Send the trip through the quote form and certificated operators bid against each other on it, sealed, without knowing who you are.

Are empty legs available on this route?

Sometimes. An empty leg exists when an operator has to reposition an aircraft along this track anyway, so the timing is theirs and not yours. They appear and vanish with little notice and get cancelled when the paying trip behind them changes. Flag empty legs on the quote form and we will include any that fit your window, but do not build a fixed commitment around one.
