FAQs for booking flights from London to Ottawa

  • Can I take a direct flight between London airports and Ottawa Airport?

    Unfortunately you cannot fly directly between these two cities, but there are plenty of indirect routes you can take that only require one stop. You can fly, for example, with WestJet from London Gatwick Airport, which requires a transfer at Toronto Pearson International first. Alternatively, you could fly from Heathrow Airport with Air Canada, which also has a change in Toronto.

  • Can I fast track through security at London airports?

    If you are going to be in a rush at the airport, or should you be travelling at peak times, there is always the option to fast track through security.

For flights from Heathrow, it costs approximately £12.50 to fast track through security.

  • Can I change my currency at London airports?

    Once you have arrived at London airports for your flight, you can use currency exchange bureaus to change your money to Canadian Dollars.

These are situated prominently in the terminals, so they will be easy to find.

    It’s easy to get from the airport to the centre as there are many methods of transport to choose from. You can get the Ottawa Airport Bus route 97 from the front of the building. This takes about 30min and costs approx. C$3.30 (£1.90).

Top tips for finding a cheap flight from London to Ottawa

  • There are two airports in London that serve the route to Ottawa International Airport (YOW) with one stop. With London Heathrow (LHR) being located so centrally, it makes it very convenient for those travelling on business. Whereas Gatwick is great for those coming from the south of London.
  • Save time on the day of your flight by staying in an airport hotel the night before. If you're flying with Air Canada from Heathrow, then you can opt for a hotel such as Aerotel, which is only a short walk from Terminal 2. At Gatwick you could stay at Hilton, which is also close to the terminal building.
  • From Ottawa Airport, it is easy to continue your journey to nearby cities, such as Cornwall in about 70min and Kingston in about 2h, which makes it a great airport if you are planning to continue your journey to other Canadian cities.

Flight attendants were great. The food I ordered was actually pretty good, and I appreciate the non-tuna snack. That long of a flight in those chairs is just brutal.

Flight attendants were great. The food I ordered was actually pretty good, and I appreciate the non-tuna snack. That long of a flight in those chairs is just brutal.

This was a red eye return, so I doubt there would be anyway to make it better. Other than adding beds.

They changed my flight twice. The 2nd time they changed it they did so the day before the scheduled departure and replaced the lie flat seat in a 777 to a 737. I paid extra to be in the 777 only for them to change it. Then the departure was delayed twice. The connecting flight was also delayed.

Direct nonstop flight was great. Flight was delayed and the crew announced a 2h delay on the sound system. 30 min or so later I hear my name on the sound system for immediate board. Several other passangers were late too. Reason: The crew incorrectly announced a 2h delay when in reality they meant a new boarding time at 2pm.

Flight was on time early arrival better entertainment good staff.everything was excellent

I don’t think there was entertainment? No mention of it. It was a good flight. Only complaint was my seat cushion was not attached and kept slipping.

LATE AGAIN. Seems like each time I use Air Canada there are delays ... extra 2 hours this time, making for a 22-hr day for me!!! The gate people did not seem to know what they were doing with loading people, unloading, checking carry-ons, letting some go ... very unorganized from Toronto to Detroit! Would have been faster to drive

The staff were on the last leg. But they were still very accommodating and polite. They were all very helpful with getting the bags up and getting people to their seats.

Flight from Lisbon to Toronto was smooth, and we arrived early! Flight from Toronto to Denver was delayed about 40 minutes. We didn’t hear about the delay until after we had boarded the plane. The delay could have been handled better.

The Air Canadian personnel were all very professional and friendly. I will definitely fly on them again.
