About flights to Ottawa

Overview

Ottawa, Canada's dignified capital, sits on the Ottawa River with grand Parliament buildings, world-class national museums, leafy parks and the historic Rideau Canal. It is a rewarding choice for UK travellers interested in history, culture and easy access to eastern Canada. The city is served by the friendly Ottawa Macdonald–Cartier International Airport (YOW). Comparing every fare in one place makes finding the right flight from the UK quick and simple.

Best time to fly to Ottawa

Ottawa has four distinct seasons. Late spring (May to June) and autumn (September to October) bring mild weather and beautiful colours, while summer is warm and lively and winter is cold and snowy, when the Rideau Canal becomes a giant skating rink. Fares typically ease outside the summer and Christmas peaks, so travelling in the shoulder months stretches your budget — check the price charts on this page for your dates.

Airlines and routes

There are currently no year-round direct flights from the UK to Ottawa, so most journeys involve one connection. Air Canada connects via Toronto or Montreal, while British Airways, Air Transat and other carriers route via eastern Canadian, US or European hubs. Total journey time from London is typically around 9 to 12 hours depending on the connection. Comparing carriers for your exact dates is the surest way to secure the lowest fare.

Things to do in Ottawa

Ottawa combines national heritage with relaxed riverside charm:

Parliament Hill: the Gothic Revival seat of Canadian government with the Peace Tower and Changing of the Guard.
Rideau Canal: a UNESCO waterway for summer boating and winter skating.
National Gallery of Canada: a glass-topped landmark housing superb Canadian and world art.
ByWard Market: a bustling quarter of food stalls, cafes and nightlife.
Canadian Museum of History: a striking museum just across the river in Gatineau.

At Ottawa Macdonald–Cartier International Airport (YOW)

Ottawa's airport sits about 10 km south of downtown, with duty-free shopping, currency exchange, ATMs and dining. The city bus and a new O-Train light-rail link connect to the centre, alongside taxis, ride-hailing and shuttles. Hiring a car is handy for exploring the surrounding region.

Top tips for finding cheap flights to Ottawa

Book roughly 2–4 months ahead for the best value — transatlantic fares climb close to departure.
Avoid the summer and Christmas peaks; spring and autumn bring lower prices.
Be flexible with your dates — midweek departures are often cheaper than weekends.
Compare connecting hubs; routing via Toronto, Montreal or a European city can vary the fare.

Travel essentials

UK travellers need an approved eTA before flying — apply online in advance.
A valid e-passport is required; no vaccinations are needed for entry.
The local currency is the Canadian dollar (CAD).

Baggage

Typical hand and checked baggage allowance by fare type for flights to Ottawa.

Cabin (hand) bag size is commonly around 56 × 45 × 25 cm — confirm your airline's limit before you pack.
Liquids in hand luggage must be in containers of 100 ml or less, inside one clear resealable bag.
Weigh your bags at home — airport excess-baggage fees are far higher than pre-booked allowances.
Extra or heavier bags are almost always cheaper added online in advance than at the airport.
