Mr Wallace was seen in the departure lounge of Dublin Airport last Friday -- raising questions about whether he was flying to Poland to attend Ireland's final Euro 2012 group game against Italy tonight.
The airline confirmed that it had been told about its presence -- and had taken action at 3pm last Saturday.
"Like all unauthorised vehicles, it was removed," a spokeswoman said.
The car park is leased from the Dublin Airport Authority, which has a contract in place with a company to tow away unauthorised vehicles.
According to its airport charges booklet, the fee for a car being towed is €140 and there are fees of €35 for each day a vehicle is kept in storage.
Aer Lingus could not confirm if it was going to investigate how Mr Wallace's BMW ended up in the staff car park.
Mr Wallace is a close friend of Socialist Party Dublin North TD Clare Daly, who previously worked with Aer Lingus.
She could not be contacted for comment yesterday.
