£141 Find Cheap Flights from Ontario to London

Flying from Toronto to London is a long-haul journey, but with the right preparation, it can be a smooth and enjoyable experience. Here are some tips to make your trip more comfortable: Choose the Right Flight – If possible, book an overnight flight (a "red-eye"). This allows you to sleep on the plane and arrive in London in the morning, helping with jet lag. Pack Smart – London’s weather can be unpredictable, so bring layers and a compact umbrella. Also, keep essentials like a travel adapter and charger in your carry-on. Use Luggage Tracking – If flying Air Canada, take advantage of their luggage tracking feature for peace of mind, knowing your bags are on the same flight as you. Stay Hydrated & Bring Snacks – Airplane cabins can be dry, so drink plenty of water. While airlines provide meals, it’s always a good idea to have extra snacks. Manage Jet Lag – Adjust your sleep schedule before departure and try to stay awake until nighttime in London to quickly adapt to the new time zone. Transportation on Arrival – Heathrow and Gatwick have great transport links. The Heathrow Express is the fastest way into central London, while the Tube (Piccadilly Line) is more budget-friendly. Have Your Documents Ready – Ensure your passport is valid, and if required, have your visa or travel authorization (e.g., an ETA for UK entry). With the right prep, your journey will be smooth and enjoyable.
