I would also add that it would be very helpful if the First would be removed from the receipt unless it was the purchased class. I have used the option of not upgrading immediately in the past, but I hated having to go back later to process the upgrade after the receipt was generated. Lately, I have been using the full version of Acrobat (not Acrobat Reader) to print and then edit the receipt. Only takes a few minutes to change the fare class to the type actually purchased if you have the full version.
