Systems, methods, and computer program products for processing exchange requests. An itinerary change request is received to modify at least one attribute of an existing ticket that includes one or more existing ancillary services. A replacement ticket and one or more replacement ancillary services may be identified by identifying a recommendation for a replacement ticket, determining whether the one or more existing ancillary services are available with the replacement ticket, constructing a search filter including category descriptions and a similarity score for the one or more replacement ancillary services, and transmitting the recommendation for the replacement ticket and one or more replacement ancillary services to a user interface.
