Ourmières-Widener worked at Air France from 1988, where she started in the maintenance team for the Concorde. Subsequently, appointed UK and Ireland Managing Director for Air France, she was then named Chief Executive of the Irish airline CityJet, after it was bought by Air France, from 1 October 2010 to 2015.[4] She was for some time part of the European Regions Airline Association.[5]
On 20 December 2016, it was announced that Ourmières-Widener was joining Flybe. She was the first woman elected to the board of 31 members. She had been appointed interim director on 24 April 2017, when Fernando Pinto stepped down.[5]
During her tenant as CEO of TAP Air Portugal, the company went through restructuring and observed positive financial growth which was also boosted by the end of COVID-19 restrictions schemes on travel of passengers.
However, such endeavours were tarnished in 2022 with scandals, culminating with the Alexandra Reis case. Reis, a state secretary of Treasure who was a board member of TAP Air Portugal then dismissed by Ourmières-Widener without the latter publicly disclosing the nature of this action, left the company with agreement on a hefty severance pay (over €500,000, to compensate the remainder of her full 4-year term contract with paid holidays) to work on NAV, another state-subsidised institute, which evoked public outcry on Portuguese society.[7]
On 6 March 2023, weeks after the public inquiry in the Portuguese Parliament about the Alexandra Reis case, and the final audit report from IGF (Inspeção-Geral de Finanças), the government dismissed her from executive duties with no severance pay.[9] In September 2023, Ourmières-Widener filed a lawsuit with the Central Civil Court of Lisbon to claim over 5.9 million euros ($6.3 million) in compensation.[10]
