Just to update on this....
at the bottom of the email receipt there is a block labelled "Receipt" which has the columns "Passenger", "Ticket Number", "Fare-USD", "Tax" and "Ticket Total", followed by "Payment Type" and "Total". This is required by 722f format.
Your receipt from the TA would be in 722g format, which is similar but I don't have a current example. The ticket number must be marked and easily visible to be IATA compliant. It sounds like you don't have an IATA 722g format receipt, when TAL is required to give you one.
I never received an email receipt and I think this has contributed to my confusion. TAL responded very quickly to my latest email and suggested I print the itinerary from the AA website (rather than just view it). I did this and it contains exactly the information you list, including two 13 digit ticket numbers beginning 001! ^
It would appear that the BA representative was giving me dodgy information and that there was never a problem. I will still be holding on tightly to the e-ticket receipt when we check-in at Stockholm mind you!
I feel that I better emphasise that TAL were very patient and helpful throughout the whole process and, other than the missing email receipt, provided an efficient and effective service to me. I would happily use them again.
Panic over I guess - thanks again for the help and for putting my mind at ease!
