I was informed that if people signed up before the 13th that they would be invited to this flight. I signed up on the 12th and ensured to fully complete the signup (dxdiag and everything) but I have yet to receive the first email stating I was invited to the flight. Will I still be invited as I signed up before the closing window that 343 stated or am I out of luck?

This tweet from @halo confirms what I was informed. Looking for answers please as I’d love to try out the flight this weekend with my friend! 
Any update on this? The flighting has started and I still haven’t gotten any email or my code on waypoint
