St George joins in an interim capacity following the departure of Norwegian chief operating office Helga Bollmann Leknes after two years with the carrier.
The airline said Bollmann Leknes elected to leave following changes to Norwegian’s senior management team.
Norwegian said Bollmann Leknes had been offered another position in the carrier’s group management team but had “decided to pursue other opportunities outside Norwegian”.
She joined Norwegian in 2017 as chief human resources officer and took on the additional responsibility as chief commercial officer in November 2018.
Geir Karlsen, acting chief executive of Norwegian, said: “I am grateful for Helga Bollmann Leknes’ contributions to Norwegian. I regret she has decided to pursue other opportunities.”
Bollmann Leknes said: “It has been a great experience to be part of the Norwegian team and I’m grateful for all the opportunities that particularly [former Norwegian chief executive] Bjorn Kjos has given me.
“Now it’s time for me to explore new adventures. I wish Norwegian and all the great people at the company all the best.”
St George brings more than 30 years’ aviation industry experience to the role, most recently as Jet Blue chief commercial officer. He has previously worked for United Airlines and US Airways.
“I am very pleased that Marty St George will be joining Norwegian,” said Karlsen. “Strengthening our commercial position in key markets and increasing our revenue-generating activities are key elements in our strategy of returning to profitability.
“I am convinced St George with his extensive experience from several of the biggest US airlines will be an asset to Norwegian,” Karlsen added.
