Which makes more sense for affiliates: Travelocity/WCT XML or Expedia/IAN XML? Please share comments on the XML (self-branding), not the normal affiliate linking programs. I am bothered that Expedia seems to not pay any hotel booking fees. And, I am intrigued by the WCT opti-fees, although I don't see why it looks like I'd get just 40% on this. What are your experiences? Ease of building? Tech support/customer service? Conversion rates? Income?
