Hi travelling4fun, whose ticket did you issue the ticket on? BA or IB? It sounds like IB.
With the IB ticket number, IB *should* be able to retrieve the ticket number. But then again, we are talking about IB inefficiency. Here we have all the airlines touting e-ticket as the way to the future , and yet when it comes to crediting of miles, no one in the FFP department knows of anything other than hard copies!
You have to get Travelocity to retrieve from their archieves the e-ticketing information. The worst they have to do is to retrieve from their archieves your PNR and your booking info. From your booking info, they SHOULD be able to get you your ticketing information which includes a copy of your ticket..!
Question - did you give your FFP number to the airline when you made your reservation, and at time of check in? Was your number on the BP?
