I used one $100 type B voucher to issue $99.70 ticket (including tax)
TA gave me $.30 refund acknowledgment customer copy.
I did not expect that since "no residual value balance on partially used coupons" is stated on the voucher.
Can I use $0.30 for next purchase?
I also called UA and asked "if I use two $100 type B vouchers for my $150 ticket, can I get $50 back?"
I was told YES... Is this true?
