Coventry Airport has submitted a new application for more than 2,000 car parking spaces, prompting fresh fears among opponents of " expansion by stealth".
However, the airport management said it was asked to make the application by Warwick District Council, the planning authority with which it has been in dispute since last March.
The Baginton airport has been embroiled in a public inquiry over its current temporary passenger terminal and faces another separate inquiry next year on a #10 million permanent terminal capable of dealing with two million passengers a year.
That application included proposals for almost 4,000 car parking spaces, many of them in the green belt.
However, in November the airport hastily purchased land from Coventry City Council which it has now earmarked for 2,060 parking bays - leaving almost 2,000 to be built if it gets a green light for the new terminal.
In the meantime, if approved, the parking application will relieve nearby Baginton village of traffic problems caused by passengers being forced to use a park and ride facility.
Archy Muir, spokesman for the Campaign Against Expansion at Coventry Airport, said: "This is yet another application from Coventry Airport for car parking and it is clear that they want to expand by stealth to more than two million passengers a year. They have no intention of following the sensible public transport targets that Birmingham has set. With Coventry Airport, it's cars, cars and more cars."
Coventry Airport managing director Bill Savage told The Birmingham Post that CAECA was "muddying the waters".
"We recently had, in open public inquiry, the direction that WDC would welcome an application where we split off part of the car parking associated with the permanent terminal and submit it now. This will have the effect, if approved and we very much hope that it will be, that we can remove the satellite car parks that bring more traffic to Baginton village."
He added: "We have never hoodwinked anyone or done anything that is against planning law."
A statement from WDC stated: "The proposal is for a layout of 2,060 spaces, 9.4 hectares in size, in association with the operation of the interim passenger terminal.
" In the accompanying statement, the airport state that, if granted, parking for passengers and employees associated with the terminal at Airport West, accessed via Baginton, would be removed.
The council considers the application is 'EIA development' - meaning it would have a significant impact on the environment.
"Consultation will take place and the application will be considered fully prior to being placed before a meeting of the planning committee for their consideration in due course."
The current public inquiry is due to run until July. A Government ruling is not expected before Christmas.
