Please excuse this off-topic rant. I parked at Melbourne Airport for 24 hours and five minutes and was charged for two days. Yes, that’s what the published fee schedule says and yes I knew it. That does’t make it fair.
Their long term car park was full. It took ten minutes to find a park in the short term so technically I was parked and using the facility for less than twenty four hours.
A fairer fee structure would be to charge by the hour for all part days. But, hey, Melbourne Airport is not run on fairness.
