Well, if it is a typo, such as John instead of Johnny on a reservation for the passenger using the lower shoe size in the workforce or class grouping into trail flow-through slot codes (ie, SAS Airlines Name Change Policy), they will tell you to take a hike. Please note that ticket fare rules can include fees associated with name changes. Full names are not typically replaced. Changes can only be made before the original departure with corresponding valid ID documents.
