Well, turns out all the worry about "texting/emailing" UC one-day passes as gifts to friends for their vacation was all for nothing. They were denied entrance into the EWR Terminal C UC Yesterday. Filled to capacity was the reason. Our friends took it in stride, just sad that our goal to send them off on their Italian vacation in style was a failure.
Now, they rarely fly and I don't fly UA. Is there any chance of us getting a refund on those UC one day passes?
