Different start and end time zone specially for flight schedules

Hi - Has anyone found a solution to create an event for Flight schedules for different start and end time zones? For example, if I am travelling from Australia to Singapore then start time zone and ending time zone of the event is different, unless I do the calculations manually I haven't found a way to enter it on Apple's calender but Google Calender has this support. I have used it a lot and it works perfectly alright but I want to transfer everything from Google's system to Apple and only thing which is holding me is a proper calender in Apple. Any solutions?

Thanks
