So, there's lots of ways to find cheap(er) airfare out there, but my point is this: if you're expecting to fly back to Cali from P'cola or Corpus with any kind of frequency, you're in for a big disappointment.
VT Skeds: Hey Ensign, we need somebody to go on a cross-country to the East Podunk, Idaho, airshow this weekend with Commander Pinksheet. Four X's and a checkride en route. You're it.
You: But, sir, I have plane tickets to go home to Cali this weekend. It's Grandma's birthday.
VT Skeds: (long silence...crickets...in the distance, a dog barks...)
I say again: from the day you start API to the day you check out of the RAG, your days, nights and weekends are not your own. You may partake of recreation and free time if the Navy has nothing better for you to do. Outside of stash/A-pool time, that will be infrequent.
