Parking prices at Melbourne Airport have been lifted again in another hit to the hip pocket of travellers, and their family and friends.

The airport, which collects almost $345,000 each day from parking charges, quietly increased prices by as much as 67 per cent on Wednesday.

The biggest relative hit is to drivers using short-term parking. The cost of parking for between 15 and 30 minutes at the airport has increased from $6 to $10.

It now costs $29 to park at the terminal for between one and two hours - up from $24.
