SELECTING ACCOMMODATIONS ON A TRAVEL CONVEYANCE

The subject matter of this specification can be embodied in, among other things, a process that includes receiving digital accommodation criteria for an accommodation assignment requested for a passenger and accessing accommodation properties that specify characteristics of accommodations offered on a travel conveyance. A first portion of the accommodation properties are base properties and a second portion of the accommodation properties are derivation properties derived from the base properties during execution of a software program configured to access the accommodation properties. The process also includes assigning weights to the accommodation properties based on a comparison between the accommodation properties and the received accommodation criteria. The process includes determining total weighting scores for each of one or more of the accommodations based on an aggregation of the assigned weights for the accommodation properties associated with the accommodation and outputting the requested accommodation assignment.
