There's little chance of volcanic ash being ejected, as this isn't underneath a glacier this time. Although the pressure built up at the site is quite high. While it may not impact transatlantic flights, if the eruption is large enough it could impact flights from & to Keflavik airport, but again there's little chance of that due to the predicted eruption site being on the east of a ridgeline, which should mean that there will be less lava flowing west.
