I fly enough to know about having to check in to the actual operating airline, but I have known people who almost missed flights because they waited in a long check in line at UA to find out that they needed to go to a far away check in desk to check in at AC.
That being the case, then a lot of airlines can't put an extra dot on their routemaps!
