3824447 - Why does the pop up appear advising that the system is searching for a lower fare for flights?

When searching by schedule I received a pop-up notification that advises the following:

Searching for lower fare for these flights. Your company has asked that we do an extra search to see if we can get a better fare for multi-carrier flights

We would like to know why it is appearing and if it can be disabled.
