Porter Airlines will begin service to Washington Dulles International Airport beginning in April.

The regional airline, which operates out of the Toronto Island airport, said it will offer three daily round-trip flights on weekdays starting April 16. It will also have one round-trip on Saturdays and two round-trips on Sundays.

“Greater Washington is a region that our passengers have told us is their number one priority for new Porter service,” said Robert Deluce, president and CEO of Porter Airlines. “We expect great interest for both business and leisure trips and look forward to bringing competition to the route.”
