Commuters and quarterly drill

[JWild]

Good evening gentleman, I rarely make a new topic as most answers can be found via search, however I couldn't find anything on this ( although I thought I recalled reading about it in regards to people doing contracting work).

My question is how do the various units handle out of state commuters, more specifically an individual from Hawaii, since they have to fly would that open up pretty much any unit? Also do some units still drill quarterly, which would mean less air travel?

Thank you for your time, I am also going to post this in both 19th and 20th Group sections.
