Occasionally, you can find a United Airlines flight that averages about 11 hours and stops in Washington Dulles International Airport (IAD). Booking further in advance is also a good solution for getting the shortest flight as emergency bookings will sometimes result in two stops and a very long flying time. When it comes to booking flights from London to Ottawa with two stops, you can find several airlines servicing the route, including LOT and KLM. Your London departure airports are Heathrow (LHR), Gatwick (LGW) and London City Airport (LCY), and your arrival airport will be Ottawa Macdonald-Cartier International Airport (YOW). What is the best way to get in and out of airports in London and Ottawa? London airports are extremely well connected to public transportation networks. The airports most commonly used on this flight include Heathrow (LHR) which has three underground stations at their terminals directly linking to the city via the famous Piccadilly Line, and Gatwick (LGW), which has its own Gatwick Express tube using Victoria, District and Circle lines. London City Airport (LCY) is also very close and can be reached via the underground tube on the DLR Line. You will also find buses from the city leaving for all airports without hassle and, of course, a taxi is also great if you have heavy luggage to consider. When you arrive in Ottawa, your destination airport will be Ottawa Macdonald-Cartier International Airport (YOW) based just 15 minutes from the city centre. You will find that the Line 97 bus is available 24 hours a day and leaves every 30 minutes to get to the city. Apart from a taxi, this would be your ideal way to get to the city centre as the train station is not based at the airport. What are the benefits of the different airports in London and Ottawa? If you are based in the centre of London and need to fly to Ottawa, consider Heathrow (LHR) to optimise your ground travel time. LHR is 15 miles (25km) from the city centre as opposed to Gatwick (LGW) which is 28 miles (45km) away. Both airports are optimal in terms of services and amenities, but Heathrow is the biggest airport in Europe. Large airports can be quite daunting for first-time travellers, and if you would prefer a smaller airport that is still world-class, consider LGW for a comprehensive solution that will take less time to reach the gates. London City Airport (LCY) is exceptionally close to the capital and as a smaller business airport, it is often much easier to get in and out whilst avoiding the crowds. Ottawa Macdonald-Cartier International Airport (YOW) will be your destination. It's a fantastic airport that is convenient, clean and easy to find your way around. Which cities can you get to from Ottawa Macdonald-Cartier International Airport? Ottawa Macdonald-Cartier International Airport (YOW) is a great destination airport if you want to be close to the inner city but still have easy access to surrounding Canadian cities and municipalities. The airport predominantly serves the metropolitan part of the city capital which is known as the National Capital Region. The closest city is Gatineau which lies on the opposite side of the Ottawa River in French-speaking Quebec. It is reachable in under 15 minutes by taxi. The airport is also based about 40 minutes from Kemptville in Ottawa, and about a 2-hour drive from Montreal. Car hire at Ottawa Macdonald-Cartier International Airport is a great solution for road-tripping in Canada to see the surrounding areas of Ottawa. Alternatively, the Ottawa Station is just 15 minutes away and you can get train tickets to all the surrounding cities with ease.
