There’s always a chance, although the annual eruptions over the past three years had a negligible impact on air travel.

The eruption site is only around 20 km (12 mi) from Iceland's main international airport, Keflavik International Airport. Due to the eruption's effusive nature with little to no ash production, it is not considered a risk to air traffic. [1]

Wasn't there another problem this time, that the eruption site is close to the geothermal plant that powers Keflavik?

At least that would only affect traffic from/to Iceland and not half of Europe though.

Iceland has a small population and a large power grid. They can survive a lot of power generation failing before things like airports start losing power.
