I have to ditto md11fr8dog here. You can find cheap seats online guaranteed.

We do have SWA tix and they're around $50 (?) per leg, space available.

My buddies not on furlough at legacy carriers complain that finding 4 seats anytime to get 2 adults and 2 kids ANYWHERE w/i the CONUS can be next to impossible. Personally, buying 1 tix and jumpseating myself (to WallyWorld for example) is enough trouble. The way I see it, unless I'm going class B to play golf, see a bud, girlfriend, etc...., I lay down the AMEX card for a fully refundable and changeable ticket.
