Greetings,
Why would "I" add "CEO" to someones name? I wouldn't. I apparently hit the "suffix" thing at some point during my reservation request. I was just happy t hat the schedule had opened up I was rushing it trying to securea good fare. (I could have done better if I had been 15 minutes quicker) I noticed that mistake and cleared it but somehow "DO" showed up.
Other than your standard titles, I would not use one. I think one looks for trouble by using such titles.
