Combine e-certificate with CS certificate?
It's been a while since I've had to do a complicated booking, and search didn't yield the answer.
I've got the elite choice $50 e-certificate, but would also like to use a PMO-DOLLARUA voucher to buy my tickets for the upcoming SFO Mega-DO.
Is there any way to book and hold the itinerary using the e-certificate so that I can go to the airport and pay the balance with the CS $UA voucher?
I'm sure this has been brought up before, so any help pointing me to the correct thread would be appreciated.
