Claims of a setback to Lydd Airport plans have been denied by managers who say expansion is too important to rush.
Applications are planned for the runway and the terminal building
Protesters had claimed expansion plans were delayed when an environmental report had to be revised, and welcomed the news as a campaign victory.
The Keep the Marsh Special coalition said it showed the Kent airport was "feeling the pressure".
The airport said a report was revised, and it was impossible to say how long planning applications would take.
Lydd Airport Action Group had claimed the revision of the report had caused planning applications to be delayed until 2006.
Terminal building 'dated'
And the Keep the Marsh Special coalition issued a statement welcoming the delay to plans that would "lead to the devastation of Romney Marsh with a huge increase in pollution, congestion and noise".
Coalition spokesman Peter Carroll said more than 7,000 leaflets would be distributed to people on Romney Marsh to explain how they could influence the planning process.
But airport managing director Zaher Deir said: "We have involved residents, local authorities and other interested statutory bodies every step of the way."
He said the revised scoping document - which sets out the scope of the environmental assessment of plans - was currently being looked at by English Nature, the Highways Agency, Kent County Council, the Environment Agency, and other bodies.
The airport intends to submit two applications - one to extend the runway and another to build a new terminal building.
An airport spokesman said the existing 1950s building was "charming but dated".
