Hi, My son is stationed in Germany at moment & is due to come home on leave this friday, his passport has expired although he has applied to renew it throught the army, still waiting on the new one arriving. Im worried about whether or not he will be allowed to fly home ?? he says he can with his travel warrant card , as he has come in & out of Germany in the last few weeks using that ... but that was via coach & going through euro tunnel ,, this will be first time flying back with no passort >> any help appreciated. Thanks T.
