Original flight from Brisbane to Melbourne was cancelled. Given this Brisbane to Sydney trip as only alternate. Meant I missed spending 6hrs with my dying mother. Delays all the way through the airport then a crappy flight to Sydney ( for a 1.5hr layover). Poor form Virgin. Customer service is no longer important at Virgin.
