No different if you checked in on line or through the kiosks at the airport.

It's the same issue if you booked through a travel agent. If they have a Sabre terminal, but booked on CO flights you're going to get a Sabre locator and a CO locator. They should be synced in real time so any change to either booking should be reflected in the copy version.

The RES systems between CO and NW are unique and very different. CO is running a IBM mainframe and Northwest is using Unisys. Northwest has a completely unique inventory control mechanism compared to Continental. I don't know that this is still true, but the International and Domestic inventory management systems at NW aren't even the same. NW still thinks it's two airlines, (Northwest Orient and Republic), in the head office in certain departments.

That being said it would be virtually impossible for CO and NW to create identical locators for every codeshare booking.
