Booked 4 return tickets on Jetstar to Wellington. Checked in online and got to the airport extra early for our 1:35pm flight. Turns out that the flight was now delayed until 2:55pm. We waited for the time to go to the gate to come around and finally got the call to go to gate 21. Got through security and was waiting in the lounge for the boarding call to come when "Attention all passengers traveling on JQ265 to Wellington, boarding will now take place at gate 23." So up we go to gate 23. Get through security and waiting in the lounge for the boarding call AGAIN, and then "Attention all passengers traveling on JQ265 to Wellington, boarding will now take place at gate 21." So down we go to gate 21 AGAIN and get through security. The boarding call came and we go to the boarding pass scanning machine and turned out our boarding passes wouldn't scan. So we had to wait until everyone else had boarded and then the supervisor came and we had to wait a further 5 minutes until they got us some boarding passes. We finally got on the aircraft and the plane was further delayed until 3:05pm because the plane had something that needed done to it. We finally took off at 3:15pm 1hour 40minutes late. And to add the crew never said anything to us exept for the safety announcement. The service is crap. Jetstar is crap
