Who operates American Airlines flight AA 1666?
In our data, American Airlines is the airline selling AA1666. Who actually operates the flight is shown on your ticket or booking confirmation.
Was AA 1666 part of a connecting flight? How is compensation calculated?
Your booking shows this, not the flight number. If AA1666 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).
