I've been trying to figure this one out - while I had thought the DOB question was a screen to make sure you knew the person and weren't "selling" access, I wonder if it's also a security precaution to avoid a changed seat assignment (few would reject a swap from e to E+, but perhaps if going Aisle to middle or something).
