I'd look on Kayak.com first, then see about discount/upgrade coupons through Amex or Costco and see where that gets you.
OT: Speaking of "topless" getting people's attention, do you remember that episode of "The Beverly Hillbillies" where Jethro Bodine noticed that all the popular places had "topless" in the name, which he figures is a restaurant where the servers don't where hats? Having Ellie Mae shilling for the place helped bring in business, but the customers were none too impressed with Granny serving possum stew, or whatever, and teasing them by removing her hat occasionally. Just an old trash TV memory...
