My horror story

I have flown with many airlines around the world regularly over the past 30 years. Both my husband and I are frequent flyers with many airlines including Qantas. Usually I would fly using Virgin but as that was unavailable, I booked a family holiday with Jetstar for an overseas reunion in January 2017, paying a premium amount for the 3 seats. We had confirmed and had seat allocation and had driven for hours with our young child as we live in the country and arrived early at the airport only to find that our seats had been sold to third party passengers fromTiger Air so we had to wait 6 hours to fly later instead. This meant that we lost our whole travel day, had to hang around at for hours at the airport consoling our young devastated child. We also had to use our mobiles to ring overseas and change bookings and confirmations for other activities and we missed the event we were flying there for. As there is no customer service at the airport and no direct contact information to speak with someone available, we then spent hours of our trip dealing with return calls from "customer service" ( when they finally called back) with no satisfactory outcome whatsoever. Effective immediately, we banned the use of Jetstar with both of our businesses for all staff travel.
