I flew Jetstar Adelaide Sydney, Sydney Honolulu.upon leaving home for flight to Sydney was advised that flight was delayed (making it to international flight was not going to happen) . Thank goodness was able to get flight on quantas. Flight to Sydney, Honolulu good.
Return flight to Sydney good.
Got to Sydney through customs etc. ok lined up at domestic for flight to Adelaide and told could not check in for another hour and half. No seats available, I am 66 and after long flight tired and no able to check in!!! Go to check in and having flown business class international I was able to take two Carry on bags
In cabin. Not able to on domestic so had to pay$150 .00 for excess. Also had paid for extra in check in luggage. Apparently international jetstar and domestic do not compute with each other.
Finally checked in after rude staff made one feel like just another piece of!!!!!!., flight to Adelaide was delayed and gate changes were made five times. Pandemonium!
They may apologise all they like but I shall avoid and discourage this airline to anyone.
