Who operates Japan Airlines flight JL 4721?
In our data, Japan Airlines is the airline selling JL4721. Who actually operates the flight is shown on your ticket or booking confirmation.
Was JL 4721 part of a connecting flight? How is compensation calculated?
Your booking shows this, not the flight number. If JL4721 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 (usually none).
