ITA works by searching for a limited time, and then displaying the results without regard to if there are additional options (that might be cheaper). In order to display the results you want, you have to use the routing rules. For instance, for your first leg, you would type "UA EWR UA FRA TG BKK TG". That would get you the flights that you want. The rest follows the same pattern, specifying the airline and the intermediate/connecting airports.
Good to see ITA wasn't too far off - thanks
