From July, the 100E Airport Express service between the city center and Liszt Ferenc will run every 6-7 minutes during the day on weekdays, BKK said.

Buses will also run more frequently at other times, it added.

The 100E Airport Express runs between the airport and Deák tér, where Budapest's metro lines intersect. It operates 24 hours a day, every day of the week.

Tickets for the service cost HUF 2,200 and can be purchased using BKK's mobile application.
