Even so, like the other examples, going through the seat maps, I noticed that there was no $ amount for first class on the domestic leg, nor was it gray X'ed out. I just tapped a seat to see what would happen, and it let me save to OU!

Can someone clarify for me: is it SOP that you become eligible on the whole itin when the first leg drops under T-5, or was this an error (on top of another possible error), and you should only become eligible as each flight in turn drops below T-5?
