We are going to go to spain in May. We have cheaper airfare thru Air France. Does anyone know if were going to have to do Customs and immigration in each country or just in France?
You will only have to do Customs & Immigration in France. Traveling in Europe is similar to traveling betweens states now.
And technically it is immigrations -- entering the country -- and not customs.
If you are connecting planes in France, you don't go through customs there, - you go through it at your final destination in Spain
