When to fly

Best Time to Fly Toronto (YYZ) to London Heathrow (LHR)

The best time to fly from Toronto (YYZ) to London Heathrow (LHR) often depends on your priorities. For lower fares, consider the shoulder seasons (spring: April-May, and autumn: September-October) when demand is typically lower than the peak summer months (June-August) and the Christmas/New Year period. Summer offers pleasant weather in London but sees higher flight and accommodation prices. Winter (November-March, excluding holidays) can also offer good deals, though be prepared for colder, wetter weather in London. Booking 2-3 months in advance is generally recommended for optimal pricing.
