In answering the question of Bumz Rush - doing business in Gibraltar is sometimes laboured and somewhat time consuming on many aspects. You may feel that you are often hitting your head against that brick wall but usually if a task is worth persuing the end result can be favourable.
Put it down to a challenge!!
The issues raised on passport control and clearance through Gibraltar is not an easy one to answer. Politically the government here must be seen to be "doing the right thing" or it can be a vote loser - and any airport agreement is naturally big news.
I suppose it could be agrued that Gib is Brit controlled and therefore subject to the same regulations of any nationals travelling through effectively Brit territory that need a visa to entry then so be it. Holders of European passports will have no problems. Further, although I have no facts and figures, no doubt Spain would be verywaryof the possibility of ibcreasing illegal immigrants through the channel of Gibraltar Airport - albeit any entry through Gibraltar followed by a quick border crossing in Spain is always met by the customery road side - frontier checks of our Spanish neighbours.
But do tell - who is the "other operator"??
