Real routes, real numbers.

One-way vs round-trip

A round-trip with the aircraft waiting is rarely double a one-way — same-day returns typically price at 1.6–1.85× because the operator keeps the crew and jet committed but flies only one leg each way. True one-ways are cheapest when your routing matches traffic the operator already needs to move; that is the entire logic behind empty-leg deals.

Repositioning is the hidden line item

Quoted prices include flying the jet to your departure airport. If no suitable aircraft is based nearby, that ferry time — sometimes an hour or more — lands on your invoice. This is why Miami–Nassau can quote below Miami–Key West on some days: dozens of jets are already sitting at Opa-locka and Fort Lauderdale.

Daily minimums and short hops

Most operators bill a two-hour daily minimum per flight day. A 40-minute hop like Miami–Key West therefore prices closer to two flight hours than to the airborne time. On very short routes, a turboprop or even a sedan transfer is often the rational call — we will tell you when it is.

When prices spike

• Holiday peaks — Thanksgiving week, Christmas–New Year and Presidents' Day add 20–40% on resort routes like Aspen, Jackson Hole and Telluride.
• Event weekends — Art Basel Miami, the Masters, Super Bowl and F1 weekends tighten supply at specific airports months ahead.
• De-icing season — winter departures from the Northeast and mountain airports carry de-ice charges of $1,500–$6,000 per application, quoted after the fact by most operators.
• International handling — Bahamas and Mexico legs add overflight permits, handling and customs overtime fees of $800–$2,500 depending on arrival time.
