I am planning a family vacation from Portland to Vancouver trying to use as miles wherever possible to keep costs down. I'd especially like to apply the scraps of miles I have on United and Delta so I can save my larger balance on AA for the flight.

It looks like only Budget offers 1-way rentals and a drop off where I need one (Port Angeles, WA). Does anyone if it's possible to use miles on United and Delta for one-way rentals? The websites don't seem to offer 1-way and I called Delta but the agent had no idea.

If all else fails AA does seem to offer vouchers that can be used for a 1-way rental but I am nervous about forking over the miles for the voucher only to find out that Budget won't accept it for one-way.

Thanks in advance for any suggestions.
