Can I buy a one week transportation card at Budapest Airport? Or maybe a single day ticket or a three day ticket?
It is not possible to buy daypass, three-day pass or a week pass at Budapest Airport. The only thing you can buy at the airport is single tickets, a package of ten single tickets and Budapest Pass. In most situations we do though not recommend the Budapest Pass, as that only is worth the money for those who plan to visit A LOT of museums and so on. For the normal usage of public transportation and maybe for visiting a few museums it is better worth simple buying a normal Budapest transportation ticket (3-day pass or 7-day pass) and later paying full entrance fee on the different places.
What to do then? As you arrive at the airport you can buy a single ticket at the Relay shop at the airport. Enter the bus, validate your ticket and travel to Köbánya Kispest (end station of the bus). There you can buy all tickets available, also the 1-day pass, 3-day pass and 7-day pass, and from there you can travel on with the metro to the city center of Budapest.
