do i fly over budapest from burgas to bratislava?

Answer 1

Yes, very close to overhead on Budapest.

Look out when they say they are about to start their descent. Budapest is 180 km before you get to Bratislava.

If you're cruising at 33,000 feet (10km) in a 737 or A319, the descent will start about 100 miles/160 km from Budapest. So if you hear the engines throttle back, you just missed it.
