Just a heads-up that Contract ID 5760339 is NOT from BJ's warehouse club. Someone posted that incorrectly awhile back and since then I've seen several posts both here and on other boards repeating the error.

That code is for travel agents who work for Carlson Wagonlit Travel, which is why the discount is so deep. (TAs get a lot of major travel discounts.)

You may or may not be asked to show TA credentials when using 5760339, which is why someone on FatWallet has posted a fake Carlson business card alongside that particular code. Personally I would never use it and feel that using a fake card is a scam bordering on fraud.

YMMV and all that.
