In a trading update, Stobart said it would continue to invest in route development, branding, marketing and airline incentive deals at the airport, plugging in £10m for this year alone.
In January 2018 Stobart launched a new executive jet fixed based operation (FBO) at the airport which is expected to cater for 5,000 flights per year by 2022.
One million passengers travelled through London Southend Airport last year after a 25 per cent rise in passengers over 2017. The airport now flies to over 30 domestic and European destinations, with the most popular choices over the past 12 months including Rennes and Amsterdam.
Chief executive of Stobart Group Warwick Brady said: "Stobart Group has made good progress during the last year. We continue to see growth in our aviation division, with a 25% increase in passengers at London Southend Airport, 10% increase in passenger numbers flying via Stobart Air, and we are excited to be welcoming passengers at Carlisle Lake District Airport from Summer of this year."
