Charter
Empty Legs, Honestly: When They Save Money and When They Don't
An empty leg is a repositioning flight priced to move. The discount is real. So are the conditions. Here is how to tell a genuine saving from a cheap way to be stranded.

In brief
Empty legs exist because charter aircraft must reposition: to pick up the next client, to return to base, to reach maintenance. Operators sell those flights at a discount rather than fly them empty. For a flyer whose trip happens to match, the saving against a normal charter quote can be substantial. For everyone else, an empty leg is a fixed route on a fixed date that may be cancelled if the flight that created it changes. This piece explains where empty legs come from, who they genuinely suit, the terms that decide whether the discount survives contact with your plans, and how TRH uses them inside a charter strategy rather than as a substitute for one.
Where empty legs come from
A charter operator flies a client from A to B. The aircraft now has to go somewhere: back to base, on to the next pickup, or to a maintenance slot. That positioning flight costs the operator fuel, crew time, and cycles whether anyone is aboard or not. Selling it, even at a steep discount, is better than flying it empty. The result is an empty leg: a specific aircraft, a specific route, a specific day, often a narrow window, offered below the price of the same flight booked on demand.
Everything about an empty leg follows from that origin. The operator did not schedule it for you. It exists because of another client's plans, and it will change or disappear if those plans do.
Who they genuinely suit
- Flyers with flexible timing who can move a trip by a day or two to match an available leg.
- Flyers on dense routes between major markets, where repositioning flights are frequent and the odds of a match are real.
- Trips where the destination matters and the exact hour does not: a weekend away, a return leg with an open day.
- One-way needs. Empty legs are one-way by nature; a round trip requires two matches or a normal charter for the other direction.
For a flyer who must be at a meeting at nine, from a specific airport, on a specific day, an empty leg is usually the wrong instrument, however attractive the price.
The terms that decide whether the discount survives
Cancellation by the operator
What it does
Sets what happens if the flight that created the empty leg changes or cancels, and the empty leg with it.
Why it matters
The operator's client comes first. If their plans move, your discounted seat may vanish, sometimes on short notice.
What to ask
- Under what conditions can you cancel this leg, and with what notice?
- If you cancel, what do I receive: a refund, a substitute aircraft at the same price, or nothing?
- Has this particular leg been confirmed by the client whose trip created it?
Where risk hides
A cancelled empty leg the night before travel leaves you buying a last-minute charter at full price, which is the most expensive way to fly.
Route, timing, and airport flexibility
What it does
Defines whether the route can be adjusted, whether a stop can be added, and how much the departure time can move.
Why it matters
Some operators will adjust an empty leg's route or time for a fee; others will not. A small change can convert the discounted leg into a normal charter at normal pricing.
What to ask
- Can the departure time move, and by how much?
- Can a different airport in the same area be used?
- What does any change cost, and does it void the empty-leg price?
Where risk hides
The route you booked and the route you need are rarely identical. Price the gap before you count the saving.
What is included
What it does
Sets whether the quoted price includes taxes, fees, catering, ground handling, and de-icing, and how passenger count affects it.
Why it matters
An empty-leg price is often quoted bare. The add-ons are the same as any charter.
What to ask
- Does the price include federal excise tax, segment fees, and airport fees?
- What is the passenger limit for this price?
- Are catering and ground transport arranged, and at what cost?
Where risk hides
A headline discount can shrink materially once the flight is priced all-in against a normal quote priced the same way.
How to compare honestly
Price the empty leg all-in. Price the same trip as an on-demand charter all-in, from a vetted operator, on the day you actually need. Then discount the empty leg's saving by the realistic chance it is cancelled and the cost of what you would do if it were. For a flexible flyer on a dense route, the empty leg usually wins comfortably. For a time-critical trip, the honest comparison often points back to a normal charter, and the empty leg becomes a bonus if it holds rather than a plan.
Before you book an empty leg
- 01Confirm the operator, its certificate, and its ratings exactly as you would for any charter.
- 02Ask whether the leg is confirmed by the originating client and what happens if they change.
- 03Get the cancellation and change terms in writing.
- 04Price it all-in and compare it to an all-in on-demand quote for the same trip.
- 05Have a fallback for the trip if the leg is pulled, and know what it costs.
- 06Book it only if the trip could move without harm.
Key takeaways
- An empty leg is a by-product of someone else's trip. Its route, date, and existence depend on that trip, not on yours.
- The discount is real when your plans are flexible and the route matches exactly. It evaporates when you need a different time, a different airport, or certainty.
- Read the cancellation and change terms before the price. An empty leg that can be pulled without recourse is worth less than its headline suggests.
- Empty legs belong inside a charter strategy: a tool for flexible legs, not a plan for essential ones.
