Changing middle name on ticket

[MStreeton10]

I have a flight book here pretty soon and I noticed that one of the tickets has my middle name on another guests ticket that I booked her first and last name are correct but the middle name is not correct.  What can I do to fix this so we won't have any issues when we depart?

You should call Southwest to have them update, there's not an online way to make the correction.

Are you both on the same confirmation number?
