Core London–US routes singled out by regulators
Competition authorities (initially the European Commission and more recently the UK Competition and Markets Authority) have repeatedly highlighted a defined set of London–US routes as being of concern under the AA–IAG joint business, and attached remedies to them.
Those London–US routes are:
London–New York (JFK and Newark treated as the New York city pair in earlier EU decisions).
London–Boston.
London–Miami.
London–Dallas/Fort Worth.
London–Chicago (particularly the premium/business segment).
London–Philadelphia (overlap created by the AA–US Airways merger, handled via separate commitments but still assessed in the same competitive context).
These routes are where regulators have imposed slot-release and related commitments (e.g., making Heathrow/Gatwick slots available to rivals, minimum “local passenger” volumes on London–Dallas, and pro‑rate/FFP access) as conditions for allowing the AA–IAG joint business to continue.
Beyond those specific remedy routes, the AA–IAG Atlantic Joint Business Agreement itself applies much more broadly to:
Transatlantic routes between the UK (and other European points served by BA, Iberia, Aer Lingus, Finnair) and the US, Canada, and Mexico.
It covers coordination on schedules, pricing, capacity, marketing and revenue‑sharing on North Atlantic services among American Airlines and the participating IAG carriers.
In practice, that means most nonstop transatlantic services operated by AA, BA, Iberia, Aer Lingus and Finnair between Europe and North America fall under the joint business framework, even though only the London–US routes listed above have special competition remedies attached.
