I'm sure it must have something to do with booking class, but I'm surprised that I'm not eligible for upgrade on a 3 hour flight from Central America. GUA-DFW-GUA segments usually have plenty of open space up front, so I'm not inclined to pay a co-pay for this. Does anyone have any experience with this situation?
