Tried to book a multi-destination itinerary today and cannot get Shares to list all available flights unless I switch to one-way search. But that won't do me any good because they won't display when I try to do my RT booking. So, I know the flights are there and space is available (over 6 months out, by the way), but there is no way I can incorporate them into my itinerary. It's like Shares was trying to force me into 3-4 hour layovers instead of the 1-2 hour ones that I wanted. Price was not an issue--I was unable to find the flights that I wanted when searching by schedule.
I called the "No-K" line and the friendly

agent told me that it wasn't possible to book the itinerary with the flights that I wanted, so I was forced to go to Orbitz to book it, and actually saved $5- over what ITA told me it would cost on .bomb--But I lose the EQM bonus for not booking on .bomb, so it is not the ideal situation.
What is going on here?!! Is it possible that UA doesn't want us to use their booking engine, which, by the way, is glacially slow compared to Orbitz???
Shares is a real POS (person of size)!
