Hi, If i make a reservation and pay to put it on hold also using an e certificate without purchasing the ticket but then cancel the temporary hold will the e certificate be useable for a future flight? I saw this in the terms and conditions for the e certificate, "15.Fare Rules: All rules of the fare purchased apply. Reservations and ticket purchases on United.com must be completed simultaneously." I do know if I purchase the ticket then cancel it the e certificate cannot be used again per the terms and conditions.
