Contact the military or your local airport for the appropriate flight information. Organizations like Welcome Home a Hero can also provide information if they have access to your local airport.
Use signs and other decorations to show your appreciation to the soldiers for the sacrifice they have made. You may also bring small gifts such as gum, bottled water or small goody bags. The gift should fit in the soldier's pocket, since she may have a connecting flight to catch before reaching her destination.
Show proper respect. Allow family members to get closest to the disembarkation point and keep any aisles clear so necessary personnel can get through.
