I am scheduled to fly Icelandair to Brussels from Seattle via Reykjavik in about 4 weeks. I just called the airline to find out whether they know anything about their flights to Brussels and whether I should be thinking about changing my booking.
The agent said they expect to resume their flight schedule to Brussels in the next couple of days, and in four weeks they expect things to be relatively normal in terms of their flights. If there was a need for a change, he assured me I would hear from the airline, and they would get me there one way or another. It seems they have been flying passengers to Amsterdam and putting them on the train to Brussels.
Even though this is the response I expected, it was reassuring to talk to someone at the airline and hear this for myself. Just wanted to share In case anyone else is in a similar situation.
