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. You need to book at least 24h in advance, and it will cost about £4 at Luton and around £5 at Stansted and Gatwick. 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

  • 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.

Not great tremendous delays instead of arriving at 8:15 pm arrived at 2:30 am next day no food gate changes. Etc

All aspects of the flight went like clockwork and staff were friendly and attentive.

We initially flew from Osaka to Vancouver and ear buds and food were all inclusive. We were surprised that from Vancouver to Toronto we had to pay for all of this - and the flight attendant did not give us what we ordered/paid for. $6 for a bag of almonds is crazy - and I asked for hummus. Very surprised we had to pay for the ear buds in order to watch the movies.

There was a mistake with the first name we only discovered at security. Air canada was unable to correct it to match then passport since it was booked through an agency. The agency could not correct it either since they need at least two hours to do that. We could not fly and lost a bunch of money. Learned my lesson about kayak.

My flight got canceled. Then AC rebooked me to a next day flight. No compensation no apology. It almost messed up my entire trip and schedule. However, all the unexpepected seems routine and ordinary to AC, so customers need to get used to.

I love air Canada. The staff is so helpful and friendly and attentive. I paid for extra room but chose a ser near a person who took up a lot of space which gave me less space than regular economy, I was sad I did that!

Really good. The staff were very helpful throughout the boarding process. The food was surprisingly good. Overall much better experience than previous one.

Because we had to drive to Toronto due to delays in Windsor on our return we had a car in Toronto so we had to drive home

Our flight from Windsor to Toronto had several delays so we had to drive to Toronto in order to catch our flight to London.

Did not appreciate “hidden fees” to check a bag for international flight and purchase a seat to be next to my spouse. Won’t choose this airline again.
