Hi all, I'm looking to the routing experts who might know why this is failing... I'm trying to add a segment to a simple LAX-ORD flight on AA. The fare code is OA14XQY1, on February 7, 2012, for $99 base. With taxes and fees, a one-way flight LAX-ORD comes up at $109. So far, so good. When I check ExpertFlyer about that fare code, I see that this routing is allowed: LAX-TUS/STL/SMF/SLC/SJC/PHX/OKC/HOU/ELP/DFW/DEN/ABQ-CHI So then I think to myself, ok, cool, let's try to add SJC (making it LAX-SJC-ORD) to pick up more miles, but I can't make it price out. The scheduling and connections are all okay, but it comes up in a different fare bucket (N) for $170. I thought maybe this was happening because it wasn't in O, so out of curiosity, I searched for just O seats flying LAX-SJC and none came up. Is that why? I'm new to this whole thing (learned it from Lucky's talk at the Chicago Seminars!) so I'm still trying to sort out all the pieces. I'd sure appreciate if someone can help illuminate what's going on.
