Hungary

if you are arriving from Prague there is no need to do anything, this is Schengen area. For leaving CZ there is nothing you need to do for sure, just check Hungary has accepted Schengen rules already (I believe so but please cross check). When passing Brno rock your wings….

Romania is not Schengen which is why you need to land at a customs airport when you fly to Hungary from Romania (or out of Hungary to Romania). Czech Republic there is no issue.

Going from Hungary to Romania, you do not need to do customs (both are EU). However, Romania is not a full member of Schengen, therefore you need to pass border control (“immigration”) on both ends.

Maybe Pecs LHPP?

Do I have this correct?

No.

All three countries involved (Czech Republic, Hungary, Romania) are EU members. They are also (consequently) members of the European Union customs union (which is about the free movement of goods).

Czech Republic and Hungary are also members of the Schengen agreement (which is about the free movement of people). Romania is not.

In flying:

• When flying between two countries that are both members of the customs union and the Schengen agreement, you do not need to do anything.
• When flying between two countries that are members of the customs union, but not the Schengen agreement, you need to pass through immigration. That’s the border police potentially checking people’s passports, visa, and what not.
• When flying between two countries that are part of the Schengen agreement, but not members of the customs union, you need to pass through customs. That’s some custom official potentially checking if you carry any goods that are subject to customs.

For you, that means when flying from Hungary to Romania or from Romania to Hungary, you need to fly from and to airports with customs facilities on both sides for each flight – because the two countries have no customs agreement in place.

so it seems the map on this page is still accurate :

sorry the post comes later than anticipated, this is about schengen.

@Patrick : Romania is a schengen applicant, not a schengen member yet it seems…

Besides the odd exception Greece. They are member of both EU and Schengen but think they can ignore the treaty by requiring every flight coming from/going to another country to fly via port of entry. A stupid hassle.

Another (positive) exception: Germany does not require customs when leaving the country, provided the aircraft is registered in the EU and it’s a private flight without goods to declare. I don’t know if there are other countries with the same concession.

All very simple stuff, isn’t it?
