When I buy airline ticket they specifically state to use name from passport. Changing official name will create impression you are not same person.

And I have my parents to thank for that in my case, through their decision not to bestow any middle name on me when I popped out of my mother's womb 70+ years ago!????

Neither of my parents had middle names. And my father always signed his name with his initial and his last name, a practice that I picked up and continued to this day. Sort of like R. Crumb (you probably remember Mr. Natural). But this is a digression from a digression... my apologies.
