As first revealed in last week’s reporting, CBS will be holding a Star Trek: Discovery premiere event in Los Angeles on September 19 — several days ahead of the global launch of the series — and today the network launched an exclusive contest for CBS All Access subscribers to win a trip to the event.

Announced today at CBS.com, US-based subscribers to the network’s streaming service — the official home of Discovery in the United States — have until September 4 to enter for a chance to win a flight for two to the L.A. premiere on September 19, along with spending cash and hotel accommodations.

Note the fine print, however: to register, your CBS All Access account must be in place prior to today — no signing up just to enter the contest.

This isn’t the only opportunity to score access to this event; as we reported last week, actor Rainn Wilson’s charity LIDE Haiti is also offering a contest for a pair of lucky fans to travel to Los Angeles for the Discovery reveal.
