Hi,
I am thinking of buying an IAD ticket using the UA DBC travel vouchers, which are each $150. When they issue the ticket, let's say for $300 using 2 $150 DBC vouchers, will the base fare show as $300 or $0?

The reason I ask is that I am enrolled in the UA Around The World IAD offer, and you must have a roundtrip worth $100.

I am wondering if I should pay with cash $100 rather than using all the vouchers to ensure that the trip reflects $100?

I know there are Type A and Type B certs, and with A they just take off the dollar amount (so above it would be $0) and type B certs are treated like exchanges. However, even if its a Type B I would think a hurried agt might just quickly enter as Type A as I think those are much faster to process?

Thanks..
