Optimizing notification transmission

A system comprising:

• one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
• receiving, by a segment service provider and from a client device of a creator client, data indicating attributes of a proposed segment;
• creating a new client-initiated segment using the attributes of the proposed segment based on the segment service provider not having an existing segment matching the attributes of the proposed segment;
• converting, by the segment service provider, the new client-initiated segment into a shared client-initiated segment, thereby enabling third parties to request, through an application provided by the segment service provider, spots on the new client-initiated segment that were not claimed by the creator client;
• identifying, from a set of clients, a subset of clients that are determined to be likely to claim one or more available spots on the shared client-initiated segment;
• transmitting, to each client in the subset of clients, data indicating that a spot is available to claim on the shared client-initiated segment;
• receiving, from a client device of at least one client of the subset of clients, a request to claim one or more available spots on the shared client-initiated segment;
• generating a request that comprises data representative of the shared client-initiated segment;
• transmitting the request to a plurality of jet operators for operating a jet to complete the shared client-initiated segment;
• receiving, from each of one or more jet operators of the plurality of jet operators, data indicating one or more attributes of a jet for the shared client-initiated segment, the one or more attributes for the jet comprising an identifier of the jet;
• and
• selecting, from the one or more jet operators, a given jet that will transport the client creator on the shared client-initiated segment using the one or more attributes of each jet.

A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:

• receiving, by a segment service provider and from a client device of a creator client, data indicating attributes of a proposed segment;
• creating a new client-initiated segment using the attributes of the proposed segment based on the segment service provider not having an existing segment matching the attributes of the proposed segment;
• converting, by the segment service provider, the new client-initiated segment into a shared client-initiated segment, thereby enabling third parties to request, through an application provided by the segment service provider, spots on the new client-initiated segment that were not claimed by the creator client;
• identifying, from a set of clients, a subset of clients that are determined to be likely to claim one or more available spots on the shared client-initiated segment;
• transmitting, to each client in the subset of clients, data indicating that a spot is available to claim on the shared client-initiated segment;
• receiving, from a client device of at least one client of the subset of clients, a request to claim one or more available spots on the shared client-initiated segment;
• generating a request that comprises data representative of the shared client-initiated segment;
• transmitting the request to a plurality of jet operators for operating a jet to complete the shared client-initiated segment;
• receiving, from each of one or more jet operators of the plurality of jet operators, data indicating one or more attributes of a jet for the shared client-initiated segment, the one or more attributes for the jet comprising an identifier of the jet;
• and
• selecting, from the one or more jet operators, a given jet that will transport the client creator on the shared client-initiated segment using the one or more attributes of each jet.
