I was a customer service sup for years while I flew and got my time and ratings, I think it helped me during the interview when I had previous airline experience according to the HR peeps. I enjoyed it, it will allow you to network with pilots and possibly find recommendations. If you have never worked for an airline before it will give you perspective to how things work. The only thing though if you go FA you time might not be fully dedicated to flying as much as you want to if you have to spend extra days cmuting to work.

Look at all those new programs eagle has to recruit pilots zero to hero to CFI and into the right seat. Obviously your financial situation will be the decision maker to it all.
