Hungary joined the Schengen border-free zone on December 21, 2007; however, the traffic changes at Budapest Airport will take effect on March 30, 2008. This means that border controls for citizens of countries in the Schengen zone will be eliminated at Ferihegy.
Budapest Airport will physically separate Schengen and non-Schengen passengers: Ferihegy Terminal 2A will serve Schengen zone flights and Terminal 2B will serve flights outside of the zone. Discount and low-cost airlines will continue to arrive to Terminal 1, which will continue to serve air traffic from both areas. The changes will not affect baggage or security controls.
