You can't wait to reserve that flight and fly off to paradise, visit distant relatives, or schedule that important work meeting. You provide all the required information, click the "purchase" button, and carry on with your everyday activities as you wait for your trip. Did you remember to include your Klm Middle Name in the reservation, though? You probably didn't, but you're not the only one. After all, we don't frequently use middle names, so leaving it off when booking an airline ticket is not unusual.
