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.
