Can anyone advise what counts as a transit passenger in airport stats, if I fly in in the morning and then out in the afternoon to another destination on the same booking is that counted as two seats, one arrival one departure or as a transit pax?

And what difference it makes? AFAIK from immigration officer POV you are in transit if you not leaving transit zone. You may be on single ticket and have layover say 6 hr and decide to get out into city, so you may or may not came back. Thus even if you transit passenger from single ticket POF, you are not from passport control officer once you pass passport control.

Serg, if you read the question it specifically refers to airport statistics, passenger numbers,  A reference to customs is irrelevant.

And what is definition of transit? If I fly to BKK, stay 2 hr in transit zone (i.e. not getting outside and not passing passport control) and then flying to LHR is it transit or not? Brain telling yes it is transit. If I stay 12 hr and still in airport? Looks like transit as well. If I came out and sleep in hotel during 12 hr layover? Where is definition? Few times I skip last leg - i.e. have a single ticket via Helsinki, but get out of the plane, never catch next one, leave airport and catch a train. How you count this situation? So I do believe that transit definition (including stats for airport) is arrival and departure without passing passport control – it called transit zone for reason. But if you leave transit zone than it is stay, even if you coming out for few hours only.

All those negative voting just make me laugh! Anyone have different opinion? Post it!
