I believe it's a coupon per segment, but could be wrong. I would go with whatever myidtravel (or whatever) says.

I'm actually hoping to go on it later this weekend, we'll see. A few tips that I've noticed, once a week they skip KSA, and it seems like those loads are a little better. It may not be the "full experience" but close enough. Also, a while ago it seemed like HNL-MAJ was the trickiest leg in most cases. Now, it's TKK-GUM. Or the opposite, depending on which way you go. Either way, I would much rather get stuck on GUM than TKK, so I would recommend going GUM-HNL for that reason.
