EU261 does not apply if the flight is to the EU and is operated by a non EU airline.
If it was departing the EU then EU261 would apply no matter where the airline is registered.
So if you had two flights operating e.g. SEA-LHR one by DL and one by BA both being delayed by 5 hours EU261 would only apply to BA.
But if the delays were LHR-SEA it would also apply to DL.
IF it's a flight (on DL) TO the EU, EC261 does NOT apply.
I said (emplasis added) "(assuming that it's NOT a flight FROM the EU so that EC261 does NOT apply)".
