This is news to me. I didn't realize you could use e-certs and put two (or more) people on the same PNR. It does sound like a pain in the neck but it's worth it, I suppose, for UDU purposes.
Has anyone had success using VDB paper vouchers and having two people on the same PNR? For example, could I call the 1K line and say I'm using paper vouchers but to put the two reservations into one PNR, go down to the airport and get it ticketed?
