I just booked flights on-line for my sister and myself and realized that I put "DR." in front of her name. Oops. She is not a doctor. I tried to back out the request but couldn't. is this going to cause problems at the airport for check-in. I assume they don't care if you are a Mrs, Miss or Ms. but Dr is more serious and I don't want her accused of impersonating someone. 

I put dd? on my husbands. I think I moved the roller thingy on the mouse. I'm not even sure what the title means.
I was wondering the same thing about whether or not I should try to change it since it says NO changes on the ticket names.
