1. Air Routes & Istanbul Transit Points
There are currently no direct commercial flights operating between Iran (Tehran Imam Khomeini Airport - IKA) and Romania (Bucharest Henri Coandă Airport - OTP). Travelers from Iran generally travel via connecting flights with a layover in Istanbul, Turkey. The two primary airlines serving this connection are Turkish Airlines (via Istanbul Airport - IST) and Pegasus Airlines (via Sabiha Gökçen Airport - SAW).
- Connection Buffer: Allow a minimum layover of 3 hours between connecting flights to safeguard against first-leg delays or transit security queues.
- Single vs Separate Tickets: With a through-ticket, your baggage is checked through to Bucharest. If purchasing two separate flight tickets, you must clear Turkish border control, collect baggage, and re-check it at the departure counter.
💶2. EU Cash Declaration Regulations (Regulation 2018/1672)
One of the most critical statutory requirements upon arrival in Romania is the European Union cash control regime. Under EU Regulation 2018/1672, any individual entering or leaving the EU carrying cash of a value of €10,000 or more (or its equivalent in any other currency) must declare it to customs authorities at the border point of entry.
This definition encompasses banknotes and coins, as well as negotiable bearer instruments such as traveler's cheques and promissory notes. Failure to file a truthful declaration can trigger substantial administrative fines and detention of the funds pending source-of-funds verification.
3. Border Crossing Realities & Clarifying the "Police Letter" Myth
A common misconception circulated across informal traveler forums references a purported "police letter" designed to ease or expedite passage through Romanian or Schengen border control. Official examination of EU, Schengen, and Romanian Border Police (Poliția de Frontieră) statutes confirms that no such document exists in the legal framework.
The only recognized police-issued document is the "Police Clearance Certificate" (Cazier Judiciar), which is strictly an administrative prerequisite submitted with your visa application at the consulate or your residency dossier at the Immigration Inspectorate (IGI), and plays no role at airport passport control. Legitimate border entry rests solely upon presenting a valid passport alongside an authorized visa or residence permit.
4. Regional Overland Travel (Tehran-Istanbul Bus Routes)
Some travelers choose to complete the initial leg between Tehran and Istanbul by international bus before boarding a flight to Bucharest. Overland bus lines between Tehran and Istanbul operate regularly, covering the route in approximately 30 to 36 hours depending on border processing times at Razi or Bazargan.
Note that tickets for these routes are generally not indexed on mainstream Western aggregator portals (such as FlixBus). Booking is typically conducted in person at coach terminals (such as Tehran West Terminal or Istanbul Esenler Otogar) or via domestic booking channels.
5. Luggage Allowance & Baggage Regulations
Permissible weight and dimensions for luggage depend entirely on the airline, fare category, and ticket terms, with no universal uniform allowance. Travelers must review the exact checked baggage and cabin baggage rules published on their carrier’s official portal prior to flying.
Always keep essential immigration papers, passports, acceptance letters, employment contracts, cash, and sensitive electronics inside your cabin hand luggage, never in checked hold baggage.
Frequently Asked Questions
Is there a direct Tehran-Bucharest flight?
No — there are currently no direct flights between Tehran and Bucharest. The standard route transits through Istanbul (typically via Turkish Airlines or Pegasus).
What are the cash-carrying rules when traveling?
Under EU Regulation 2018/1672, any traveler carrying €10,000 or more (in any currency) when crossing an external EU border must declare it to customs. Since Romania is an EU member and arriving from Iran counts as crossing an external EU border, this rule applies to you.
Is there such a thing as a "police letter" that eases crossing Schengen borders?
We found no official EU, Schengen, or Romanian document by this name that facilitates entry or transit. What does officially exist is a "Police Clearance Certificate," required for visa and residence applications, not for easing routine border crossings. If you have heard of a "police letter," it is most likely an informal, undocumented practice, not a guaranteed legal procedure.
Is there an international bus between Istanbul and Tehran?
Yes, bus routes between these two cities genuinely exist, but they are usually not listed on international booking aggregators (like FlixBus) — booking is mainly done in person at the Istanbul bus terminal or through local/Persian-language booking sites.
How much luggage am I allowed?
This depends entirely on your specific airline and ticket fare class and changes often — always check the exact carry-on and checked baggage allowances directly on your airline's official website (such as Turkish Airlines, Pegasus, or others) before flying.
