KLM will only fly to Curaçao on Tuesdays for the next three weeks. The flights are operated with the largest Boeing of the fleet, the 777-300.
On Wednesday the aircraft left with a respectable occupancy of passengers headed back to the Netherlands, Good Friday there will be an extra cargo flight to bring medical equipment to the island. This is being done in collaboration with the Dutch government. That plane has three people in the cockpit, but no flight attendants on board and will, therefore, fly back empty with the same crew on Saturday after the mandatory rest period.
