Now Open..Gate Slots LHR. B6, F9, AC Invited..

Airlines have been invited to apply for slots between London and the US that are being made available as part of interim measures imposed by the UK’s competition regulator.

The move forms part of the Competition and Market Authority’s (CMA) investigation into the Atlantic Joint Business Agreement (AJBA), which involves oneworld alliance members American Airlines, British Airways, Iberia, Aer Lingus and Finnair.


The CMA has directed the carriers to make slots available at either London Heathrow (LHR) or Gatwick (LGW) to allow eligible airlines to operate up to seven round-trips per week on each of the London-Boston, London-Dallas/Fort Worth and London-Miami city pairs.

The slots will be available for four consecutive IATA seasons, starting from summer 2022. Professional services firm Mazars, which is monitoring the process for the CMA, has set a deadline of July 1 for any airline wishing to apply.


The CMA began investigating the AJBA in 2018 to examine the joint venture’s impact on UK-US routes. It assessed the competition from other airlines on each route and the benefits that the AJBA may deliver including improved schedules, connections and new routes.
Following the investigation, the regulator identified possible competition concerns on routes between London and each of Boston, Chicago, Dallas, Miami and Philadelphia.
