Cheapest Toronto to London Flights — Combinations You Haven't Tried

Toronto → London is one of the cheapest transatlantic corridors out of Canada, with Air Canada, BA, Air Transat, and Icelandair all competing on a relatively short flight. Most travelers search one airport pair on one set of dates and book what they see. SnagRid tests 100+ valid combinations across origin airports, arrival airports, stopover hubs, and flexible weekdays — and surfaces the cheapest one with the booking order that locks the savings.

Why this route has hidden savings

Three Toronto-area origins, four UK arrival airports, and meaningful price gaps between full-service and leisure carriers mean the optimal combination shifts weekly.

Airport options on both ends
Toronto has 3 viable origin airports (YYZ, YTZ, YHM). London has 4 arrival airports (LHR, LGW, STN, MAN). Each pairing has its own fare distribution — most search engines never test more than one.
Stopover hubs that beat direct
One-stop routings via Reykjavík (Icelandair), Dublin (Aer Lingus), Montreal regularly undercut the direct fare on this corridor — and some carriers throw in a free multi-day stopover as part of the ticket.
Date flexibility you're not using
Shifting departure by even one weekday inside a ±3-day window frequently flips fare class on this route. The cheapest months historically are January, February, October, but fares still swing 30%+ week-to-week within those months.
