Proposal: Additional properties related to flight boarding passes

Boarding passes often have information which is not currently modeled in
schema.org. To that end, I propose the following new properties on
FlightReservation:

passengerSequenceNumber: The passenger's sequence number as assigned by the
airline.

passengerPriorityStatus: The priority status assigned to a passenger for
security or boarding (e.g. FastTrack or Priority).

securityScreening: The type of security screening the passenger is subject
to.

And on Airline:

boardingPolicy: The type of boarding policy used by the airline (e.g.
zone-based or group-based).

The RDFa can be found at

Thank you for your consideration,
