I think that's pretty standard practice with both Delta and Continental these days. There's always a MR or MRS at the end of my and my spouse's first name. There's no space between our first names and the titles, either. On a Continental itinerary that I just checked, my middle initial also follows my first name and precedes the title, so three things are all run together as one word. Thus far, we haven't had any problems with security as a result of it.

May I share a funny but non-related story with you? Once I lost my job, and the family was on COBRA till the next insurance kicked in.

In the meantime, I went to a dentist, he was not sure about this insurance, I said, I'll pay cash and get reimbursed later, just do the filling.

My real name is Faina. The check was issued to: Faina Cobra Dayenu. The happiest reaction was from my husband: I finally know your real name

Thanks fluffnfold, very reassuring!
