Per seat, commercial domestic flights are cheaper. However, when you compare total value — especially for groups — the gap narrows significantly. A commercial flight from San José to Quepos for 4 passengers might cost $60–$100 per person each way, totaling $240–$400. A private charter for the same group starts around $700 and gives you: your own aircraft, flexible departure time, direct routing, no lines, and departure from any airport. For business travelers and luxury tourists, the time savings and comfort alone justify the difference. For families or groups of 5+, the per-person cost of a charter becomes very competitive.
