For international travel, you must show documents at the airport even if you do OLCI. However, the OLCI webpages that I've seen for international flights all ask for passport information, including the name on passport, so this might have the effect of flagging your situation.
If OP has already changed driver's license, I assume that the decision not to continue using maiden name has already been taken, but I do wonder why change one's name?
