I understand that from reading the entire thread, but I would assume that the policy regarding downgrades is probably the same whether it is INTl or Domestic or if it isn't they are probably 2 sections of the same "policy". Numerous posts cite "the policy" but no one other than Channa cited anything specific. If you prefer, I would be happy to edit my post and remove the details of my particular flight and simply ask how I get a copy of the policy Channa referred to or the current UA policy on (INTL) downgrades.
