I'm a UA newbie. Is it possible to use a 10% electronic certificate and or a current miles bonus promotion for tickets that have already been purchased ( but not flown)? I have flts booked/paid for that would qualify for an e-certificate I've just received and also a miles bonus promotion they has a booking start date after my purchase date (Australia/US travel). I've spoken with UA in Australia and they aren't interested in my E-certificate but then again I've found that they generally have little idea about many of UA's offerings.

Thanks....
