Who operates Aegean Airlines flight A3 773?

In our data, Aegean Airlines is the airline selling A3773. Who actually operates the flight is shown on your ticket or booking confirmation.

Was A3 773 part of a connecting flight? How is compensation calculated?

Your booking shows this, not the flight number. If A3773 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 (€400 per passenger (EU261)).
