I "get" the round trip pricing on the AA website. What I don't get is when you start crazy positive, then start mixing in multi thousand dollar negatives on the return choices and end up with math that doesn't work well. I got so frustrated I went over to BA and purchased my AA tickets from them. Try JFK-BUD in J in July. You get an $8,000 price RT on the outbounds, then when you go to the returns you get $X,000 negatives for pricing, all leading to a ridiculous final price. This without mixing classes of service. Can anyone explain this as a glitch or is this a new era of pricing where prices need red ink to handle negatives during searches?
