Please feel free to move this into the combined "questions about electronic travel certificates" thread if you can find it -- I wasn't able to find it with FT's search engine or with Google.

I picked up a electronic travel voucher in exchange for volunteering to be bumped from an oversold flight this weekend and I have a couple of questions that should be totally obvious but aren't explicitly in the t&c:

1) Can I use it more than once until I've used up the entire balance? (For example, if I have a $200 voucher, can I buy a $120 ticket and then an $80 ticket using the same cert information?)

2) Is the expiration date (1 year from now) for ticketing only, or also for travel? (Can I buy a ticket on 10/29/2011 for travel on 12/31/2011?)
