British Airways is going head-to-head with Cityjet, launching a high-frequency route between Dublin and London City Airport this autumn. The showdown between the pair comes just weeks after Cityjet was sold by Air France-KLM to Germany's Intro Aviation.
It also pitches BA against another new entrant to the route, Flybe.
Cityjet is the biggest operator at London City Airport and its service to Dublin, where the airline is based, is one of its busiest.
British Airways will operate a five-times-a-day service from Dublin to London City on weekdays and once a day on both Saturdays and Sundays. It will launch the route in October.
The competition from British Airways, which is part of the IAG group that's headed by Willie Walsh, pictured, comes as Cityjet is trying to plot a growth and profitability path. The airline carried about 2.2 million passengers last year. It has been loss-making for years under Air France-KLM's ownership, but aims to break even next year.
Cityjet's chief executive Christine Ourmieres previously said that she believes the airline will be able to grow profitably after being unshackled from Air France-KLM, which had limited the ways in which Cityjet could sell its tickets, for instance.Ms Ourmieres owns 7.5pc of Cityjet following the acquisition of the carrier from Air France-KLM.
