What is the difference between ‘welcome aboard’ and ‘welcome on board’?


The expression aboard is older than on board, however, the two expressions can be used interchangeably to mean on/onto a ship, plane, train, or bus:

  • Jack was already aboard/on board when he remembered that he’d left his suit at home.
  • The plane crashed, but everyone on board/aboard survived.
  • Are all the passengers aboard/on board?
  • This is your captain speaking. Welcome aboard/on board of this British Airways flight.

Welcome on board/aboard can also be used figuratively when welcoming a new member of a team:

  • Welcome on board/aboard, James always speaks very highly of you.
  • Welcome, Janine. It’s good to have you on board/aboard!
