The U.S. Transportation Department (USDOT) Wednesday imposed a $135,000 penalty on British Airways over a 2017 tarmac delay in which it failed to ensure the timely deplaning of passengers. As part of a settlement, the airline, which is owned by IAG , agreed to cease and desist from future similar violations. USDOT said British Airways must pay $67,500 within 30 days and the rest within one year if the airline violates the order.
