A great gift idea for your dad who loves traveling could be a scratch-off world map where he can keep track of all the places he has visited. Another option could be a portable luggage scale to help him avoid overweight baggage fees. You could also consider getting him a guidebook to a country or city he has always wanted to visit, or a travel journal to record his adventures. If he enjoys photography, maybe consider buying him a new travel camera or a subscription to a travel photography magazine.
Or you can get him a star map with an important date you share.
