Traffic to Budapest from Western Hungary enters the city in this district; a main road, Budaörsi út is the direct continuation of motorways M1 and M7. Three bridges on the Danube are located in the district; the bridges Liberty, Petőfi and Rákóczi/Lágymányosi connect the district to the neighboring 5th and 9th districts on the Pest side.

Kelenföld Railway Station, the fourth largest railway station of Budapest is in the district. Most of the trains heading to Western Hungary and Western Europe pass through the station (including commuter trains to the agglomeration). The district also has a smaller station, the Albertfalva station.

Kelenföld Railway Station is also the terminus for Metro Line M4; the line, opened in 2014, is the first of the Budapest Metro to serve the district, where it has 5 of its 10 stations. It connects the district with Keleti Railway Station, the largest railway station in Hungary. Next to the Kelenföld Railway Station there is also a major bus station for local buses and another for buses serving the nearby towns.

The district has 46 bus lines, 9 night bus lines and 11 tram lines (among them Lines 4 and 6, two of the most important tram lines of the city, both of which have their terminus in the district).

There are no airports with scheduled flights within the district, however, it is home to Budaörs Airport, the pre-1950 main airport of Hungary. This was the second international airport in Budapest (after Mátyásföld Airfield), and the oldest still existing one, although today it serves general aviation only. During World War I one of the first military airfields, Albertfalva Military Airfield was located in the district, next to the first Hungarian airplane factory.
