Trying to book BKK-CDG March 4, 2014 as part of a multisegment trip. On expertflyer, ana and united, there are 2 first class seats showing as available for award travel.

4 different USAir reps have said first is not available, but business is. Business is not showing available on expertflyer, ana or united.

Any help to help them see the award availability in first would be appreciated. All other segments of a complicated itinerary are all set.
