I have posted many a thread where the information you all have provided me has been vital and trip-saving. This is not one such thread. No complaints, no issues...just simple curiosity here:

I just finished booking UA tix for my parents. When doing so, I noticed that there was the option to chose the passenger as "adult 18-64" or "senior 65 and up" (a category they fall into) along with various children age selections. There was no difference in fare when trying adult vs. senior. No special options were offered upon continuing with the booking as a senior. It shouldn't be a data collecting/demographic collecting issue since we are required later to provide a DOB which would provide UA with much better/usable demographic information.

So I was just curious....does selecting "senior" ever have any impact on anything?
