Peel Airports Group is in talks with potential investors over a possible sale of part of the business.
In a statement issued today Peel said: "The contemplation of a partner follows a number of approaches and is consistent with Peel's strategy of developing greenfield assets into attractive infrastructure investments."
Peel owns and operates three UK regional airports in Liverpool, Doncaster Sheffield and Durham Tees Valley.
Neil Pakey, deputy chief executive of Peel Airports, said: "Liverpool is now one of the UK's major airports and has been less affected by the current aviation slowdown than most other airports. Peel has grown the airport from 0.7 million passengers to 5.4 million passengers in just over 10 years and it is well positioned for continued development."
Peel also said it is building 15,000 sq ft of additional retail space and a new passenger security search area in Liverpool.
