When booking through our system I will get the GDS PNR, the selling carrier PNR and the ticket number. If it's a codeshare I will also get the operating carrier PNR which is a critical piece of information for accessing the booking for seats, pre flight info and documents, check in, etc. Spaces for all of these would be great. For the codeshare situation, maybe a conditional operating carrier PNR field that only appears if the system detects a codeshare, even prompting you for it so that clients have that key piece of information.

There should be a button for Record Locator for flights right in the booking. This should not be confirmation #. I need my clients to be able to clearly see it written out for them.
