Hi,

Recently changed to a company in which I buy my own tickets and expense. At my previous employer travel was booked via Concur and a company credit card so I never had to manage cancelled tickets and residual value.

I have a flight tomorrow BOS to EWR on a non-refundable ticket that I am going to cancel. Domestic, coach, and fare value is about $130.00. I already SDC'd this from today to tomorrow and I doubt weather will get so bad I'll have the option for a cancellation fee waiver.

Questions:
1. If I cancel this will UA bill my credit card an additional $70.00 to reach the $200 change fee?
2. I am still expensing this, so will I be able to get a receipt for the cancellation?

Anticipating a future issue like this, as a hypothetical if the fare was, say, $500:
3. Then UA would keep $200 and I would have $300 remaining for a new ticket, correct?
3a. If there is $300 left over from the hypothetical ticket how do I apply that $300 to a future ticket purchase?

Apologies if this has been answered a dozen times and thank you for the insight.

Mike
