Month ago flew Darwin to Perth, ticketing said 737 seated row 26, got to the airport to find the flight was a A320 seating row 5. At least the flight was on time and staff most pleasant, good trip. Friends who we were to meet in Perth were booked QF Newcastle to Perth via Adelaide arriving much the same time as we. The flight to Adelaide was cancelled at the last minute and were put on a J* flight to Brisbane thence Perth, arriving 4 hours later than originally planned, they were not happy.
