We used Delta last year and the bags going to SXM and coming home were NOT for free no matter what! Check with them carefully. It's the only place they charge for bags. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Yikes.gif" alt="" />
Pretty sure pat was referring to American Business Class and the no charge for bags.
I do think if you have a certain Delta credit card you do get ONE checked bag at n/c.
We've actually paid less than that for high season AA r/t in Business for Saturday n/s flights, and they allow you three bags each with the weight limit of 70# each.......
