I have flown jetstar 6 times and have always been on time (flights and me). as for the flight closed, it does state CLEARLY that you should be there 60 minutes prior and any later than 30 minutes prior and you will lose your flight and no refund so perhaps read the fine print in future? they are a great BUDGET airline with great prices. as the old saying goes you get what you pay for so if you want to pay double or triple and arrive with 10 minutes to spare go for virgin or qantas. I have always flown from avalon to adelaide brisbane and sydney so maybe being a small airport we get better treatment? just my 2 cents worth.
