  • Clears customs
  • Re-checks all bags onto a connecting UA flight (all on the PNR)
  • One or more bags are lost.

Or should the Montreal Convention NOT apply since the only remaining flight left was the purely domestic flight (for purposes of a lost bag)? It goes without saying, all of the international legs were completed.
