Per the CBA, on a VTO line, you get the credit hours for your vacation @ 6 CH * # Vac days. ie. 10 days vacation = 60 CH. If, and a big if, they are building lines more than your vacation hour credit, they go by what you request, but it can not be during your scheduled vacation time or 48 hour buffer on either side if you so request.

Lately, you'll get anywhere close to 56 - 60 hours total. Normally, they'll build you up to the RLG number.

So to answer your question, it depends on how much vacation time you have. If you only have 7 days, you'll probably get some extra trip(s).
