I purchased my mom a ticket on CX a few weeks ago. She has a Chinese first name and in her travel documents, her first name has a hyphen in it. i.e. Abc-Def. When I entered it in the system I entered it as Abc Def since it wouldn't let me enter the hypen at the time of booking. Will this pose an issue for her? Should it have been just run together as AbcDef instead?
