Cheap flights from London to Ottawa

The expensive stretch runs through December and Ottawa's summer, with April the cheapest month on this route. January, February and March sit between those peaks, while May and June offer a middle ground before summer; October and November can be useful shoulder months if your dates are flexible. Weekday departures and returns are worth comparing with weekend dates, and connections through holiday periods should be checked carefully.

What a fare includes starts with the ticket type: some itineraries are priced with bags, seats and changes bundled in, while others add each extra at checkout. All carriers named here fly London to Ottawa with at least one connection, and none offers a nonstop, so compare United Airlines, Delta Air Lines, KLM Royal Dutch Airlines, Air France, Turkish Airlines, Icelandair, Aer Lingus, LOT Polish Airlines, BA CityFlyer and WestJet on the same dates. A cheaper base fare can become the dearer one once bags and seat selection are added.

Arrange your transfer before you land if you arrive late, travel with children or carry heavy bags, because Ottawa International is outside the centre and the first hour is easier with a plan. The usual choices into town are taxi, bus or a pre-booked car, and the right one depends on your arrival time and luggage; check terminal details, ground-transport hours and whether you need to clear formalities before meeting your driver. Watch for the gap between landing and reaching your accommodation, and keep your documents and address handy for the driver or transit.
