The leg
Aspen to St Thomas
The great circle track from Aspen to St Thomas runs 2,505 nautical miles on an initial heading of 108 degrees true. A super midsize jet covers it nonstop in roughly 5h 47m, before winds.
This is where aircraft class starts to matter to your day, not just your comfort. A light jet may need a fuel stop that a super midsize does not, and a stop costs forty five minutes to an hour on the ground plus the fuel to climb back to altitude. The clock change is 3 hours ahead in winter and 2 hours ahead in summer, because the two cities shift their daylight saving rules on different dates.
Nonstop capability starts at the super midsize jet class on this route, with the Bombardier Challenger 350 the smallest airframe we would put on it without a stop. A further 3 aircraft can do it nonstop on a good day, and those are the quotes worth reading carefully. A marginal leg becomes a fuel stop the moment the winds turn, the cabin fills, or the departure field is hot and high. 16 of the aircraft we track cannot make it without stopping at all, which does not rule them out. A stop on a cheaper airframe sometimes still wins on total cost, and the bid comparison will show you whether it does.
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 Aspen. Most charter traffic uses Aspen Pitkin County (KASE / ASE). The credible alternates are Eagle County (EGE) and Garfield County (RIL). 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.
Aspen restricts aircraft wingspan to 95 ft and sits at roughly 7,820 ft elevation in mountainous terrain. Operators require specific crew qualification, and weather can close the field with little notice.
Arriving St Thomas. Most charter traffic uses Cyril E King (TIST / STT). The credible alternates are Henry E Rohlsen St Croix (STX). Pick the one closest to where you are actually going. The airport with the famous name is frequently the wrong answer.
Ask the operator to confirm ramp availability and customs hours for your specific date. Parking at popular fields is the constraint people forget, and it is usually what pushes a departure by an hour.
| Airport | ICAO | IATA | Metro | End | Role |
|---|---|---|---|---|---|
| Aspen Pitkin County | KASE | ASE | Aspen | Departure | Preferred |
| Eagle County | KEGE | EGE | Aspen | Departure | Alternate |
| Garfield County | KRIL | RIL | Aspen | Departure | Alternate |
| Cyril E King | TIST | STT | St Thomas | Arrival | Preferred |
| Henry E Rohlsen St Croix | TISX | STX | St Thomas | Arrival | Alternate |
Cost
What moves the number
The honest answer to what this costs is that it depends, so here is precisely what it depends on.
- 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.
- Fuel and stops. A technical stop costs fuel to climb back to altitude, a landing fee, handling, and forty five minutes to an hour of ground time.
- De-icing. Winter departures from northern fields add de-icing, which is charged by volume of fluid and can be a serious number on a large aircraft.
- 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
St Thomas 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.
Atlantic hurricane season runs June through November. It rarely cancels a trip outright, but it does move departure windows, and travel insurance is worth reading properly rather than skimming.
Mountain fields are the ones that reward planning. High elevation cuts engine performance, summer heat cuts it further, and the combination reduces how much weight the aircraft can lift. Winter brings snow closures and de-icing. Both seasons can change which aircraft the operator will put on the trip.
Questions
ASE to STT
How long is a private jet flight from Aspen to St Thomas?
The great circle distance is 2,505 nautical miles, which is about 4,640 km. A super midsize jet covers it nonstop in roughly 5h 47m block to block. A heavy jet flies the distance in about 5h 43m, and a light jet in about 5h 51m 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 Aspen to St Thomas nonstop?
No. This leg needs about 127 percent of a light jet's published range, so plan on a fuel stop or move up to a class with the legs for it. The smallest aircraft that does it nonstop with margin is the Bombardier Challenger 350.
Which airport should I use in St Thomas?
Cyril E King (TIST) handles most charter traffic. The alternates are Henry E Rohlsen St Croix (STX). Choose on ground time to your final address rather than on the name you recognise.
Do I clear customs on a private flight from Aspen to St Thomas?
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 Aspen to St Thomas 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.
