This is not an English question - it's about travel rules. In the US, it would not matter at all. What matters is if the tickets say "Maggie" but your ID says "Margaret" or your tickets say "Rick" but your ID says "Richard."
I'm not aware of any airline that would deny your boarding because your title is wrong. If it concerns you that much, talk to your travel agent, but it's not a matter of fauly English.
