Who operates Ryanair flight FR 1731?
In our data, Ryanair is the airline selling FR1731. Who actually operates the flight is shown on your ticket or booking confirmation.
Was FR 1731 part of a connecting flight? How is compensation calculated?
Your booking shows this, not the flight number. If FR1731 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 (EU261), or £350 if UK261 applies).
