ами аз разгледах отново сайта и намерих това:
"Budapest Airport is relatively well accessible also by Public Transportation Means. Passengers are taken by a direct bus service from Terminals 1 and 2, called the ’Airport Bus’, and, from now on, passengers are taken by bus 93 from Terminal 1 to Kőbánya-Kispest"
На тебе ти върши работа ’Airport Bus’, ето го неговото разписание и спирки: http://www.bkv.hu/busz/repter.html
Дано съм ти помогнала поне малко.
