Brussels Airlines canceled more than 75% of its flights Wednesday due to a pilot strike.

It was the second of two announced strike days for Brussels pilots this week with the first having taken place Monday.

Brussels flies two U.S. routes; Brussels-New York JFK and Brussels-Washington Dulles.

Flights to Brussels from Washington and New York were among those the airline planned to operate Wednesday. But flights to the U.S. from Brussels weren't part of the carrier's truncated schedule for the day.

The Lufthansa Group carrier is offering all customers that had been scheduled to fly Wednesday free rebookings for travel before June 30 or full refunds, regardless of whether their flights were canceled.
