With about 350 km between KSC and VIE (short-haul (up to 1,500 km)), compensation may be €250 per passenger (EU261), if you are entitled to it. All amounts

Does EU261 apply to Austrian Airlines flight OS 654?

Who operates Austrian Airlines flight OS 654?

In our data, Austrian Airlines is the airline selling OS654. Who actually operates the flight is shown on your ticket or booking confirmation.

Was OS 654 part of a connecting flight? How is compensation calculated?

Your booking shows this, not the flight number. If OS654 was part of a connecting journey on one booking, distance is counted from the first departure airport to the final destination, and the delay is counted on arrival at the final destination. The distance band (short-, medium- or long-haul) follows that distance and may then differ from this leg (€250 per passenger (EU261)).
