I booked in December to fly from AKL to BKK return with Jetstar in May. Everything was fine until 3 weeks before the departure when, for some unknown reason, I was emailed a copy of my itinerary which I had already received back when I booked my tickets. Fortunately something caught my eye as I went to file it and upon inspection, they had changed 2 of the sectors to completely different days (in one case, 2 days later)! There was absolutely nothing in the email heading to alert me to the changes and had I not noticed it, the trip would have been a complete disaster. Contact with the call centre was useless ( 4 phone calls with differing degrees of English spoken and no supervisor available for me to speak to) and all I was told was I had to take those options (at no charge to myself I was told) as the other flights were no longer flying. Luckily I didn't take their word for it and kept an eye on their website. I found that the first flight had only had a time change ie: was leaving 40 minutes earlier than previously and the second flight was still operating on the day and at the time we had booked. Fortunately my husband took over and got a helpful person at the call centre who fixed everything up for us...at no cost to us... as if they were doing us a favour!! My point is check your emails carefully and NEVER take what you are told by the call centre as gospel...check it out yourself. Despite all this, they are our only LCC option from NZ now that Air Asia has pulled out so will probably use them again.
