Will be flying F9 for the first time on a connecting flight to LAS.

Since F9 doesn't participate in TSA pre-check, generally how long are the lines to pass through security at MIA's G gates at or around 8 am? I'll be heading there from the Concourse D, and assume I'll have to pass security again.

Some general questions:

1. Will only have a laptop bag with me and assume it's free so long as it is within there 18 x 14 x 8 requirements?

2. Downloaded their app. I assume there's an option to show it on email or add it to Apple Pay to use for scanning on entering security and the aircraft?

Thanks!
