An empty leg is not a sales problem: it is a geometry problem. And Central American geometry is more favourable than it looks.
The cost you are trying to avoid
A flight from San José to Drake Bay is 83.5 nautical miles. If the return runs empty, half the operation does not produce while consuming fuel, airframe hours and crew time all the same.
The goal is not to sell that leg back to someone. It is not to generate it in the first place.
The short chains that already exist
Southern Costa Rica has a density that allows rotations without returning to the Central Valley:
| Sector | Distance |
|---|---|
| Palmar Sur – Drake Bay | 17.3 NM |
| Golfito – Puerto Jiménez | 10.0 NM |
| San Isidro – Quepos | 25.4 NM |
| Guápiles – Tortuguero | 26.9 NM |
Four hops under twenty-seven nautical miles. At those distances, adding a sector to a rotation costs very little against what it costs to depart again from San José.
The typical southern rotation
An example of how it is built, with real distances:
San José → Palmar Sur (76.3 NM). Large-group entry into Osa, which is where the higher category earns its keep.
Palmar Sur → Drake Bay (17.3 NM). A short hop almost nobody plans as a flight of its own, but which is very cheap to add once chained.
Drake → San José (83.5 NM) with return passengers, if there are any.
Against the usual alternative — San José–Drake out and back, one leg empty — the chain has more sectors and fewer unproductive miles.
Where the logic breaks
Worth saying before someone applies it badly:
Small fields do not chain the same. Punta Islita is eight metres wide. If the rotation is carrying the larger aircraft, that hop cannot be made. The specific aircraft is assigned on confirmation, based on passenger count, baggage and the destination field.
Ground time adds up. Four short sectors with passenger turnarounds at each can consume more crew duty than two long ones.
And demand has to exist in the right direction. A chain only works if there are passengers on every link; otherwise two empty legs have become three, and the planning has made things worse.
What it takes to plan them
Two things a small operator does not always have:
Visibility of demand in advance, to know whether the second link will fill before committing to the first.
And a reliable distance grid. The catalogue holds 5,019 verified distance claims between fields in Central America and the Caribbean. That is the raw material of any rotation planning. Operators we bring on evidence current certification, insurance and fleet documentation before receiving a first assignment.
The short criterion
Before selling an empty leg, check whether you could have avoided generating it. Selling a repositioning recovers part of the cost; chaining well avoids creating it.
The first is damage control. The second is planning — and only the second scales: an operator can sell a handful of empty legs a year, but cannot sell all the ones a bad rotation generates.
Frequently asked questions
What is an empty leg?
A sector with no passengers, usually repositioning or return. It consumes fuel, hours and crew all the same.
Which short chains exist in the south?
Palmar Sur–Drake 17.3 nautical miles, Golfito–Puerto Jiménez 10.0, San Isidro–Quepos 25.4 and Guápiles–Tortuguero 26.9.
Why does chaining pay?
Because at those distances adding a sector costs little against departing again from San José.
When does it not work?
If a field restricts the rotation's aircraft, if ground time exhausts crew duty, or if there is no demand on every link.
What does planning them require?
Advance visibility of demand and a reliable distance grid between fields.
Sell the empty leg or avoid it?
Avoid it. Selling recovers part of the cost; chaining well avoids generating it.
