I was a flight attendant for Southwest for 8 years. It was a good job, but the lack of control over my own life REALLY got to me a lot. Plus, passengers can be PRETTY crazy (Airline has it pretty dead-on....oh, the stories I could tell.)
Know that, unless you are willing to move to a base city, you will probably not be based in your home town. That means, either getting a "crash pad" with classmates (depending on how many you share it with...$200-500 per month), or renting an apartment in your commuting city.
You will usually start out "ready reserve", which means being "on-call" 24 hrs a day for 4-day periods. You get "per diem" for every hour that you fly, plus bonuses if your plane is full, so if you are not used on ready reserve...expect your checks to be even smaller.
I'm glad to see that SWA's initial rate is higher now. When I started, it was $13.10 per "trip" (appx. one hr in flight...each day's travel can be 4-8 "trip" pay). When all was said and done, flight attendants in Oakland qualified for (and many received) food stamps.
So, if you are commuting to a base city to do ready reserve, you will have to travel non-rev the day before your reserve starts, stay at alternative housing, and non-rev back the day after your duty ends. Expect to be gone for 6 days a week when you first start. Depending on the seniority of your base...that could last anywhere from a few months, to many years.
Over the 8 Christmases that I was a flight attendant, I NEVER had a Christmas and Christmas Eve off. The first few years, I was usually scheduled to be gone Dec 23-26. Then, I would hold trips that got me home for Christmas evening, and then I would get trips that would get me home on Christmas Eve. Unfortunately, one of those years, many flight attendants were calling in "sick", and I got JA'd when we touched down at my home base. My dh was waiting for me in the airport (I actually did have a 102 fever, and desperately needed to be relieved). I had to "kiss him goodbye" and go back out. It was pretty tough. If you get JA'd....it can be an immediate dismissal to refuse the assignment...even if you are sick. I also knew a girl who got JA'd from home on her dd's 5th birthday...that was tough, too. My b-day is July 3rd....so, I never got my birthday off in eight years, either.
I am not trying to discourage you from becoming a flight attendant. I enjoyed my years as a flight attendant, and had I stayed, I would be making over $40 per trip right now...that's pretty good pay!!! But, I knew when to get out. I went out on maternity leave in July 2001, and after 9/11 knew I would never be returning. One look at my dd...and, I was DONE!!!
As far as benefits...interline specials are great (they even have great discounts to WDW). Your parents will get to fly free (although, non-reving is not all what it is cracked up to be), and you will get to see a LOT of the US, or world depending upon what carrier you choose.
But, the job is a lot of work, and not much glamour. Just know what you are getting yourself into, so your expectations are realistic.
