IAG Cargo is strengthening its summer 2026 schedule with a new direct route between London Heathrow and St Louis, alongside broader capacity growth across North America, Canada and Asia.
The new four-times-weekly service between Heathrow and St Louis will begin on 19 April and marks IAG Cargo’s 27th destination in the United States. The company said the route will provide the only direct connection between London Heathrow and the Missouri hub, improving access for freight forwarders serving manufacturing and aerospace supply chains in the US Midwest.
Beyond St Louis, the summer schedule includes increased frequencies on several major US routes. Services from London Heathrow to Chicago and Washington Dulles will rise from 14 to 21 flights per week, while flights to San Diego and Austin will double from seven to 14 weekly services.
The network expansion also includes additional widebody capacity between London Heathrow and Madrid, aimed at improving feed into transatlantic services and giving freight forwarders more routing flexibility between Europe, North America and Latin America.
From Madrid, services to San Francisco will resume. On the Asia side, IAG Cargo will also increase frequencies between Heathrow and Tokyo Haneda to double daily, strengthening Asia-Europe connectivity.
Canada is another focus area. Capacity between London and Vancouver will increase from seven to 10 flights per week, rising further to 14 weekly services during July and August. In addition, a new daily service between London Gatwick and Vancouver will operate between May and September.
Camilo Garcia Cervera, chief sales and marketing officer at IAG Cargo, said the schedule is designed to give freight forwarding partners more choice and flexibility across key trade lanes. He said the addition of St Louis opens new access to the US Midwest, while the broader increases across North America, Madrid, Haneda and Canada strengthen support for time-critical and high-value shipments.
With hubs in London, Madrid, Dublin and Barcelona, IAG Cargo offers global connectivity across six continents. London alone provides capacity on more than 700 weekly widebody services, while Dublin operates around 100 weekly widebody transatlantic rotations. Madrid and Barcelona together contribute 275 weekly widebody connections across North America, Latin America and the Caribbean.
The company also said it continues to develop its portfolio of specialist products, including its recently launched AOG service for urgent aircraft parts movements.
