Curiously, in perhaps 10 RTW tickets issued open-dated (so perhaps 150 segments) I have only once ever had any question at all at check-in, and I very rarely have the ticket number entered in the reservation. (The once was at AY at HEL where they basically had never seen this tyoe of ticket before and they were fairly clueless about OneWorld in general.)

Any sectors for which you have a reservation should be visible online. Talk to your travel agent - mine uses Abacus and hence http://www.virtuallythere.com The reservations are independent of the ticket so there is no need to have ticket numbers in the reservations unless the airline insists on it to hold the reservation (and in this case a good TA can normally just invent a ticket number to keep them happy). Sometimes I don't know until quite close to the time of travel which ticket I will use for a sector, so it is not always possible to associate the number anyway.
