Porter Airlines has signed an interline agreement with Icelandair that gives passengers on its flights access to Europe on a single combined e-ticket, the Toronto-based airline announced Wednesday.

The agreement allows passengers can book a single combined e-ticket for Porter Airlines and Icelandair flights and check baggage through to their final destination.

How does it work?

The deal makes it easier for a Porter customer to seamlessly transfer onto an Icelandair flight with few hassles, for a trip on to Iceland and Europe.

Porter and Icelandair currently share a number of destinations, including Halifax, Boston, Washington-Dulles and New York-Newark. So theoretically, a customer could board a Porter plane at the airline's hub at the Toronto Island airport, and then easily switch to an Iceland-bound flight in one of those mutually served airports, and travel on to Iceland or one of Icelandair's 20 European destinations.

"This is Porter's first interline agreement providing access to Europe," said Michael Deluce, Porter's chief commercial officer.

"Icelandair has numerous gateways within our network that passengers can fly from."

Icelandair provides service to Iceland from several North American cities and offers connections to more than 20 cities in Scandinavia, Britain and Continental Europe.

Icelandair recently expanded its seasonal service from Toronto's Pearson Airport to a year-round operation and resumed seasonal service from Halifax with up to three flights a week.

Porter is a regional airline based at Billy Bishop Toronto City Airport.
