If you have an AC membership, & are in an airport w/an AC, ask the AAngel to print the receipt for you. It will be on ticket stock & you will have to search for the fee/fare breakdown amongst all the tiny print, but it should be there.

There is another thread, somewhere (started by me, btw), about the lack of receipts for change fees. Apparently this was another one of Discount Dougie's enhancements which required the pax to submit a written request, along w/a check for $15 (seriously) in order to get a receipt for a change fee. I complained to the DOT about it & it seems, from at least one flight I had to change after, that perhaps this has been rolled back.

I have another flight I have to change in the next couple of days, so I will be anxious to see what comes on the e-mailed itinerary.

With a straightforward ticket, page 3 of the e-mailed itinerary, after the trip is ticketed, works just fine for me & none of my clients have ever rejected it.
