There have been no Halo Infinite flights released at this time. If you are talking about Halo Reach / MCC then you may need your email. If you were invited to the steam flight there would be a steam key which is required. If it was the MS store flight, you can open up the Xbox Insider Hub and as long as you are signed in with the same account t you used to sign up to the Insiders program, you will be able to see the build in the Hub and download it from there
