My personal opinion is that you should reach out to them with any updates. I think it's very likely that you won't be accepted if you haven't heard anything yet, but it's worth some kind of shot. I recently reached out to a handful of schools with a new publication, so I am following my own advice
I was in the same boat - I had to schedule various flights, but was waiting to hear back from UC Berkeley's comp bio program since it would impact my flight plans. In the end, I just emailed Kate Chase (the admin), explained my situation, and she responded to let me know that I had been rejected. If you email her, you may get an answer!
