I'd like to book a RT from DCA-AUS. ITAmatrix is showing an option where the connection time in DFW is 5 hours 5 minutes. Unfortunately, AA.com or Travelocity will not show me this routing and I want this large connection time in DFW so that I can check out the Centurion lounge. The options available are ~1 hour connections. Is there any way I can choose my own segments(with the 5 hour connection) without paying the phone booking fee?
