Can the aeroplane make it?
Range here is usable range — book range at long-range cruise, less a reserve allowance. It is the figure that decides whether the leg closes, and it is the question most mappers do not answer.
Wind, month by month
The same business jet at Mach 0.85 and FL410, in each month’s average upper wind. MMMY to MMUN is quickest in February (1h 55m) and slowest in June (2h 05m); MMUN to MMMY is quickest in July (2h 05m) and slowest in February (2h 20m). The wind column is the average along-track component: plus is a tailwind.

Monthly means for 1991–2020 from NOAA’s NCEP/NCAR Reanalysis, at the pressure level nearest the cruise (about FL387), along the great circle. An average is smoother than any one day’s jet stream, so a given flight can see much more or much less; airlines also move the track to use the wind, which this does not. More in how wind changes block time.
How far from an airport?
Nowhere on the great circle is more than 45 minutes from a suitable airport at the one-engine diversion speed Overfly uses (430 kt in still air), so a twin-engine aircraft flies it under the 60-minute rule, with no ETOPS approval needed.
A suitable airport here is one OurAirports classes as large with a runway of 8,000 ft or more. An operator’s real alternates also depend on weather, fire cover and approval, and its diversion speed on the type. More in equal-time points and ETOPS, explained.

Questions people ask about this route
How far is it from Monterrey (MMMY) to Cancún (MMUN)?
782 nautical miles. That is 1,448 kilometres or 900 statute miles, measured as a great circle between Monterrey International Airport and Cancún International Airport.
How long is the flight from Monterrey to Cancún?
About 2h 05m block time for a business jet cruising at Mach 0.85 at FL410 in still air, including 30 minutes of taxi, climb and descent. Wind moves that figure in either direction — eastbound across the North Atlantic or the Pacific it can be an hour or more. This page is deliberately still-air so the figure is stable and citable; to apply the month's average upper winds from NOAA, open the route in the mapper and switch on seasonal winds.
How much does wind change the flight time between Monterrey and Cancún?
In the average upper wind, Monterrey to Cancún at Mach 0.85 runs from 1h 55m in February to 2h 05m in June, and the return from 2h 05m in July to 2h 20m in February. Those are 1991–2020 monthly means from NOAA's reanalysis; on a given day the jet stream can make the difference larger or smaller.
What is the initial bearing from Monterrey (MMMY) to Cancún (MMUN)?
109° true at the departure point. A great circle changes heading continuously, so this is the initial bearing, not a constant one.
Which aircraft can fly Monterrey to Cancún non-stop?
Of the types Overfly carries, G650ER, G550, Global 7500, Falcon 8X, Falcon 7X, Challenger 350, A350-900, B777-300ER, A320neo, A320, B737 MAX 8, B737-800, An-124, Concorde, King Air 200, ATR 72, Dash 8 Q400 clear it on usable range — that is book range less a reserve allowance.
