The best flights from Toronto to London

The overnight flights from Toronto to London are too short for a full nights sleep. You'll lose most of the day you land in London to the urge to sleep. It's a false economy, unless you really can write off the day that you land.

The dayflights might require an early morning start to get to the airport, but this will help you adjust to the earlier timezone in London. Stay awake throughout the flight, then reset with a full nights sleep in a proper bed when you land.

If you have to take the overnight flights, there are two ways to do it:

Option 1: Take the latest flight. Eat dinner before you board, then decline all the drinks, dinner & breakfast service onboard. Try to sleep through the whole flight. You'll land in London later in the day, so it won't be as long until you can reasonably go to bed again.

Option 2: Take the earliest flights, then go to sleep in London. These flight land around dawn, but if you treat it more like a long evening on Toronto time, then go to bed you land, waking up around lunchtime. This works if you can spare the morning, and you can get home or to wherever you're staying before the morning traffic hits.

Studies show the effects of lower cabin altitude (more oxygen and humidity) help with feeling less fatigued when you land.

787s, A350s and A380s have lower cabin altitudes than other aircraft. On long flights, like from London to Toronto, you'll notice your skin, mouth, and nose dry through the flight.
