Find a good deal on your flight from London to Sarnia with Netflights. If you want to keep your options open, take a look at flights from another airport in London.
But when you fly is just as important as where you fly from. Search by month to find out when flights are at the priciest and their cheapest.
Another way to get a cheap flight is to book last minute – but this does mean you may not be able to get the exact flights you want.
Once you’ve chosen your flight, why not check out our deals on accommodation and car hire? You’ll find lots of hotels in Canada, including some close to the airport – perfect if you're arriving late or leaving early.
