How bad is the overnight bus from Budapest to Prague compared to a 6 AM flight?

Hi everyone,

I’m trying to decide how to travel from Budapest to Prague and would appreciate some advice.

The flight option leaves Budapest at around 6 AM, which means I would probably have to wake up extremely early, get to the airport in the middle of the night, and still sleep pretty badly anyway.

Because of that, I’m considering taking an overnight bus instead. There are options with RegioJet leaving around 11 PM and arriving around 6 AM, and FlixBus options leaving close to midnight and arriving around 6 AM.

For those who have done the Budapest–Prague route by overnight bus: how comfortable and punctual is it? Is it realistic to get at least some sleep, or would you still choose the 6 AM flight instead?

Thanks!
