You would be best served to call the Airline issuing the ticket (e.g. 016 UA Ticket stock). Appears to me to be very unique situation that I would do everything to avoid misunderstandings at check-in/during trip.
Booking through Travelocity may result in Airline telling you to secure answer from booking agent (Travelocity) which would make me more cautious and dubious that any guidance that you get is going to be honored by the Airline.
Hope others have better insight than I can offer.
Good Luck!
