According to Budflyer, you will be able to reach Thailand with a direct charter flight from Budapest in February and March next year.
Good news for travellers: the Italian airline Neos Air will launch a new charter flight between the Hungarian capital and Thailand. The flights will operate once a week between 22 February and 29 March. You may travel on Boeing 787 Dreamliners on the Budapest–Phuket route. Hungarian travel agencies have begun to advertise the relevant travel packages in recent days, Budflyer wrote.
After a long while, this is the first direct Budapest–Thailand flight to commence operations. Surveys suggest that passengers would prefer a direct Budapest–Bangkok flight most of all.
