My flight on Icelandair from BOS-KEF was detailed for over an hour due to the fuel truck delivering fuel late to the plane.

As a result, I will miss my 8am connection from KEF-CPH (on my same ticket).

I am traveling in business class.

The next from KEF to CPH on Icelandair is at 2:30pm, 6+ hours later than my originally scheduled arrival.

They're is a flight on SAS from KEF to CPH at 11:45, which is 3:45 later.

I don't know what the airline intends to do.

What comp am I entitled to under EU compensation if I am rerouted on my connection on either of these?
