Liverpool John Lennon airport handled 4.3 million passengers in the last financial year to leave it 10% off pre-pandemic levels.
The Merseyside airport saw volumes rise by 15% year-on-year in the 12 months to March 31.
Revenues for the same 12-month period rose by 14% to 44.4 million.
A statement said: “Rising passenger numbers have been driven by continued recovery of the travel sector and significant investment into the airport.
“The investment and continued high performance of the airport is attracting new airlines, leading to new routes for customers and an overall improvement in the airport’s already leading customer experience.”
Jet2 started flying from Liverpool airport in the past year and has since expanded its programme for summer 2025.
Airport chief executive John Irving said: “We have continued to make significant improvements at Liverpool John Lennon airport as we look to return to pre-Covid passenger numbers.
“Everyone who works at the airport is dedicated to providing our faster, friendlier, easier experience for all of our customers.”
He added: “We are actively exploring how we can better accommodate increasing passenger footfall while maintaining our high standards for customer service.
“We are also investing heavily in projects which will enable us to enhance the airport, maintain our compliance with the latest regulations and support our carbon reduction initiatives.”
