Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, are described for contiguously seating passengers in a travel conveyance. In one aspect, a method includes receiving a seat request for multiple seats, and, in response to receiving the seat request, calculating factors associated with each seat in a set of eligible seats. The method includes defining an initial set of seats as a subset of the set of eligible seats, defining a set of factors for each seat in the initial set of seats, associating a priority with the multiple factor sets, where the factors include multiple contiguity and vacancy factors, the contiguity factors being of a higher priority than the vacancy factors. The method includes processing the factors based on the priority to identify an anchor seat from the initial set of seats, assigning the multiple seats based on the anchor seat.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, are described for a reservation system. In one aspect, the reservation system can receive a request to select a preferred accommodation for a customer from a user of the reservation system, identify available first accommodations from a plurality of accommodations, and determine that the preferred accommodation for the customer is not available for selection by the user from the available first accommodations. In response, the system can place the request for the preferred accommodation on a waitlist. In response to receiving an indication of an occurrence of an event, the system can automatically identify one or more available second accommodations from the plurality of accommodations, determine that the preferred accommodation for the customer is available for selection from the one or more available second accommodations, and assign the available preferred accommodation to the customer.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing actions including receiving booking data for one or more customers, receiving profile data for each of the one or more customers, receiving operational data, processing the booking data, the profile data and the operational data based on one or more unit eligibility rules, each unit eligibility rule of the one or more unit eligibility rules including one or more conditions and one or more actions associated with the one or more conditions, generating an eligible unit group index based in the processing, and providing the eligible unit group index as input to a unit selection engine.

Abstract: 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.
