AY 3668 (AY3668) is sold by Finnair. On a codeshare another airline may operate the flight, and the operating airline determines which rules apply.
Neither EU261 nor UK261 usually applies to flights from United States to Canada. If the flight was part of a booking that started in the EU or the UK, the rules may still apply.
Does EU261 apply to Finnair flight AY 3668?
Usually not, unless AY3668 was part of a booking that started in the EU or the UK.
Who operates Finnair flight AY 3668?
In our data, Finnair is the airline selling AY3668. Who actually operates the flight is shown on your ticket or booking confirmation.
Was AY 3668 part of a connecting flight? How is compensation calculated?
Your booking shows this, not the flight number. If AY3668 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).
