Pretty sure my ticket says JSBHJR (concatenating) the last name with Jr on international but only last name for domestic.
TSA Pre is not available for international itineraries.
FWIW, DL IT has similar fits with hyphenated names. SkyMiles will take it, but they won't issue tickets with them, but the TSA will accept them.
