A ten-year action plan at Ronaldsway Airport will cost around £120 million, according to Infrastructure Minister Tim Crookall.
He faced a question for written reply from Douglas Central MHK Chris Thomas about the Isle of Man Airport Masterplan.
Mr Crookall said the draft masterplan is being put together to go before Tynwald by the end of this year, with a number of what he called "remedial and strategic actions".
He said that work would cost £120 million over the next 10 years, although work is continuing to finalise that estimate.
