Hey everyone...this question will point out my newness to Expertflyer, but I was doing a search for RT flights from SGF/ORD Oct 28/Oct 30. I see on expert flyer the following Available Classes on AA... Y7 B7 H7 K7 M7 L7 W7 V7 G7 S7 N7 Q7 O7 When I go to available fares, the Q and O fares don't show up (they are also missing from AA.com searches). The first fare class seems to be N at almost $500 (over $0.50/mile). What am I missing here...shouldn't hte O and Q fares be available for sale? Do they require a married segment (if so how do I see this)? How do I get the deeper discounted tickets? I was hoping to get to attend the October FF Seminar in Chicago! Thanks for the help!
