I've never tried these e-tickets/print at home (and don't think I ever will), but if I buy two tickets, one for myself and the other for Mrs 34D, do I need to specify her name and her own credit card number at the time of booking?
I use e-ticketing for all of my VT Advance runs (I know they're non-changeable, but then again neither is an Advance AFAIC) and with them it is the
lead passenger (The passenger making the booking i.e; The person whose account is logged-in to the VT website) whose name and identity details must be provided, and - If said ID is the card used for payment - That person
must travel and have the same card in their possession for that ticket to be valid. However passports and driving licences may also be entered for this purpose, and I
think this could be used to legitimately buy an e-ticket on behalf of a third party.
I've never had a second passenger on any of my bookings, but it is
possible that their name might need to be entered and will likely appear on the ticket if so. It's also worth noting that e-tickets have ample space for several passengers' names on them, so - Presumably - A group of eight passengers travelling e-ticket would all be issued on the same document, rather than eight separate tickets.
To clarify: If you were to book a trip for yourself and your wife and provide your name as the primary passenger, it is your name and ID that would be used to validate the ticket as good for travel. Your wifes' name may also appear on the ticket nonetheless however, and it might be wise for her to carry suitable proof of her name just in case ye get an overzealous RPI.
However in all of my VT advance runs over time, I don't think my ID (Debit card) has been requested on more than two occasions.
Of course; If your wife was to book her own ticket, she would have to supply her own details and ID information as stated above.
Sorry if this has rambled on a bit, but hope it's useful all the same.
