Confused abt single entry schengen visa & Air Travel between Schengen countries

[Rizwan]

I'm pakistan national,I have got Schengen visa from hungarian embassy in Islamabad, of type C and single entry for buisness purpose and my wife will accompany me with same visa for tourism purpose.

My plan is that i want to go to Greece and Italy for one day stay each  before going to hungary and one day stay in Paris on way back to pakistan.

Now my confusion is that when i will take flight (Air Travel) from Greece to Italy or from Italy to Hungary , will it be considered as leaving Schengen area? and our passports will be marked as EXIT and visa expires? or it is ok do so with single entry schengen visa.

Greece, Italy, and Hungary are all part of the Schengen zone, so traveling within these countries does not require multiple entry visa.

Short stay visas (C): for stays of 1-90 days’. This visa in general grants free mobility within the Schengen territory for visiting, as well as business and tourism purposes with stays of a maximum of 90 days per 180 days of the year.

I got this from Hungarian Embassy Website in Pakistan..
