For give my ignorance

I need to fly on partner airlines and book travel through corporate software (concur) as Delta themselves cannot accommodate my travel needs in this unusual circumstance.

I will receive miles but not MQM correct?
How does Delta even know in flying?
Is it possible to obtain upgrades with my Delta status? (Im currently plat with a reserve card but will be diamond by then)


Travel Nov 1st last flight out of Hilo Hawaii 8:15pm on Hawaiian Airlines, connects in HNL but then it gets tricky, ultimately arriving in Ft Lauderdale around 4-6pm November 2nd- it would be an airlines change and there are options of using Virgin and I think something else.

ANY advice/opinions would be greatly appreciated.
Have sky lounge access.
Work pays for tickets and doesn't balk too much over prices.
