Like everyone said go to the first one that offers a job. If you get both look at the business plans and history. Every Legacy airline even in the good old days have ups and downs. They seem to find a way to furlough every 6 or 7 years (whatever the reason they just do). SWA on the other hand is rock solid and getting better. You want a place to retire from so look at the way they do business.
On paper SWA would be more solid/more money, but I can't imagine never flying international. Tough call, good luck.
