Abstract: A method, apparatus, system, and computer program product for planning multimodal travel. A planning request for the multimodal travel from a first location to an second location is received. Candidate routes are determined for a passenger that is customized for a set of customization parameters a using the first location, the second location, and a set of passenger preferences. A candidate route in the candidate routes comprises a first leg from the first location to a first vertiport via a first modality, a second leg for a passenger air vehicle to travel from the first vertiport to a second vertiport using an air modality, and a third leg from the second vertiport to the second location using a second modality. The candidate route in the candidate routes is selected to form a route for the multimodal travel for the passenger when a user input is received selecting the candidate route.

The method includes receiving a flight plan of an aircraft indicative of a plurality of landing sites and a corresponding plurality of flight legs. The method includes determining an energy load of the aircraft associated with each flight leg. The energy load corresponds to an amount of fuel used during the flight leg.
