Literal
He [topic-は] 9-o'clock departure New-York bound [possessive-の] shuttle-flight [to-に] jumped-on.
９時発 ('departing at 9') + ニューヨーク行き ('bound for New York') are standard transportation label compounds. シャトル便 is 'shuttle flight/service.' 飛び乗った ('jumped onto') is a compound verb conveying urgency — he barely made it. The transportation compounds are high-frequency patterns for reading timetables and signs.
