Cain makes accessing historical invoices easier

We have updated the link that can be used to access historical invoices for both expense and informational purposes. Previously this link required both the traveler's last name and the record locator to access a historical invoice. The link can now accept the traveler last name & airline ticket number. As the airline ticket number is generally provided on credit card statements (while the record locator is not), this update makes it easier for the traveler to benefit from this resource.
