I type this as my flight JQ286 has left literally minutes ago- without me.
I arrived 5 minutes after the check-in time and walked to the self check-in counters, only to find that the flight was no longer on the screen. I walked up to the Jetstar counter and asked if they would be so kind as to check me in- I was told that I was "5 minutes late" and that the next available flight would be at 4pm (my flight left at 6:55am, I was at the airport just a couple of minutes after 6:25am).
I had to spend over 300NZD to purchase a last-minute flight with Air New Zealand.
Those Jetstar twats just stood there, knowing full well that they could have checked me in as I was only a couple of minutes late! To add insult to the injury, the flight was paging for passengers well after I had spoken with those two muppets. I called the Jetstar 0800 number (couldn't find an e-mail address to send a flaming e-mail to) only to be told that I should have been at the airport AN HOUR before the flight departed.
Fuck Jetstar. Fuck their deceptively low airfares. Fly with them and you'll inevitably end up spending a good deal more than what it would have cost you to fly with a proper airline in the first fucking place.
