I don't know whether this deserved it's own thread but I am sitting in the SIN QF F Lounge after waiting at the gate for a while before being advised by the Captain that they have discovered issues with one of the engines after landing in SIN. The aircraft is serviceable and the engineers will need to replace a valve. We have been given a new departure time of 23:00 changed from the original departure of 20:20. Qantas has also given everyone SGD20 (simply show your boarding pass) that can be used at the Transit Area buffet, Burger King, Delifrance and Texas Chicken. The lines at each are very long so I will stay in the lounge and go back for some dinner later. It was also a nice gesture how the captain and crew came out to talk to passengers about the delays and ensure that everyone understood that they could have free dinner. With 2 incidents in one day in SIN I can imagine Qantas is going to cop further beating in the media. Obviously this is a 747 and not an A380 and I hope the 2 issues are not related. It will be interesting to see what time we actually get to MEL in the morning and whether I will be able to make my 9:00am connection.
