Frequently Asked Questions about Buying Cheap Flights to Serbia from Portugal

How can I find cheap flights to Serbia from Portugal?

To find cheap flights to Serbia, start by being flexible with your travel dates. Flying mid-week or outside the high season, such as autumn, can significantly reduce the price of flights from Portugal to Serbia. Use the TICKETS.PT price comparison tool to see flight offers to Novi Sad and Belgrade from various airlines flying to Serbia. Activate price alerts to be notified when there is a Serbia-Portugal flight promotion, helping you buy Serbia tickets at the right time. Consider flights with layovers, as they can be cheaper than direct flights from Portugal to Belgrade.

What is the best time to buy cheap air tickets to Serbia?

The best time to buy cheap air tickets to Serbia is generally 2 to 3 months before the departure date, especially if you are looking for cheap flights from Lisbon to Belgrade. For the high season (summer), buy 4 to 5 months in advance. Autumn (September and October) is when cheap flights to Serbia are most likely, as demand decreases.

Always check TICKETS.PT to see the available round-trip Serbia flights and low-cost flights to Serbia options at the time of your search.

What is the main airport for flights to Serbia?

The main entry point for those traveling to Serbia is Nikola Tesla Airport (BEG) in Belgrade. Most international flights, including those from Portugal, land at this airport.

However, it is always advisable to check the latest entry requirements before buying round-trip Serbia flights, especially if your trip is extended or has a purpose other than tourism.

Practical Travel Guide: What to Know Before Flying from Portugal to Serbia

Prepare for your trip to Serbia with these essential tips. Understanding local logistics and customs will make your travel experience much smoother and more enjoyable.

Portuguese citizens traveling to Serbia for short stays (up to 90 days within a 180-day period) do not need a visa. Only a valid passport or Citizen Card is required for entry. However, it is mandatory to register your presence with the local police authorities within 24 hours of arrival. If you stay in a hotel, they will do this for you; if you stay in private accommodation, the host must handle the registration. Always keep proof of registration, as it may be requested upon departure.

The official currency is the Serbian Dinar (RSD). Although some tourist spots accept euros, it is best to use the Dinar for daily transactions. You can exchange money at exchange offices (lower commission) or withdraw from ATMs. Credit cards are accepted in major cities and modern establishments, but in markets or small shops, cash is king. Remember that Serbia is not part of the Eurozone, so check exchange rates and bank fees before traveling. Avoid exchanging money at the airport, as rates are usually worse.

In Belgrade, public transport consists of buses, trams, and trolleybuses. The ticketing system is based on an electronic card called 'BusPlus', which must be validated for every trip. Buying the card and topping it up is more economical than buying single tickets. Taxis are common, but make sure the meter is running or negotiate the price before starting the journey to avoid surprises. For intercity travel, the bus network is extensive and reliable. Trains are slower and less frequent but can be a scenic option. Renting a car offers freedom, but traffic in major cities can be chaotic.

Belgrade and Novi Sad offer a wide range of accommodations, from luxury hotels to budget hostels and rental apartments. For a more authentic experience, consider staying in central neighborhoods like Stari Grad or Vračar in Belgrade, which are close to attractions and restaurants. In smaller towns, look for 'konaks' (traditional guesthouses) for a local touch. Booking in advance, especially during high season (summer and holidays), ensures better prices and availability. Always check if the accommodation offers the mandatory registration service with the authorities.

Serbia is generally a safe country for tourists, but it is always wise to be careful with pickpockets in crowded areas, such as markets or public transport. Serbians are known for their hospitality; a handshake is the common greeting. Coffee is an important part of the social culture, and people tend to drink slowly and socialize. Tipping is not mandatory but is appreciated (around 10%). Avoid discussions about politics or recent history. Do not dress too informally when visiting churches or monasteries. Learning a few words in Serbian, such as 'Hvala' (thank you), will be very well received by locals.

Serbian food is rich and hearty, with strong influences from the Balkans, the Mediterranean, and Central Europe. Be sure to try 'ćevapi' (grilled sausages), 'pljeskavica' (Serbian hamburger), and 'sarma' (stuffed cabbage rolls). For cheese lovers, 'kajmak' is a must-try. The national drink is 'rakija', a strong fruit brandy served as an aperitif. Turkish coffee is popular, but Serbian wine has also been gaining prominence. Look for 'kafanas' (traditional taverns) for an authentic meal and cozy atmosphere. Portions are large, so don't over-order!

Roaming can be expensive as Serbia is not part of the European Union. The best option is to buy a local pre-paid SIM card (operators like MTS, Yettel, or A1) at the airport or kiosks in the cities. Wi-Fi is widely available in hotels, cafes, and restaurants in major cities. If you plan to use your Portuguese mobile phone, check your operator's international data packages before traveling. Serbia's international dialing code is +381. Mobile coverage is generally good throughout the country, except in some more remote mountainous areas.

To have a richer experience in Serbia, try to step off the usual tourist paths. Instead of just visiting the sights, wander through Belgrade's residential neighborhoods, such as Dorćol, and discover their small cafes and craft shops. In Novi Sad, explore the street culture and local markets. Talk to locals – they are usually very open and proud of their country. Accept invitations for coffee or rakija; it's a great way to immerse yourself in the culture. Use public transport to feel part of the city's rhythm and look for local festivals or events happening during your stay. Dive into the nightlife, especially in Belgrade, which is famous for its 'splavovi' (floating clubs on the river).
