I live on GUM and UA's VP of Transatlantic and Transpacific Operations, Jake Cefolia, was here on a "listening" tour back in October. The questions was asked about a non stop specifically between GUM and LAX and his answer was that it was not in the immediate or long term plans, but that they're constantly evaluating route opportunities. I say scrap a non stop GUM to west coast flight for GUM to IAH as a number of travelers for GUM are federal government workers/contractors and even military personnel heading to CONUS for some meeting/conference/training.
