I flew SIN-MEL on Monday night (2240 from SIN) and the flight was quite empty - numerous rows with only 1 person in there (10 across 773ER - A6-ECG)
I'm quite surprised as this is the first EK flight i've taken that wasn't jammed full of people (Normally flying to Amsterdam, Auckland or London Heathrow from Sydney)
No Y->J points upgrades available via EK website even though there were seats spare.
It doesn't really bother me to be honest... the Y cabin crew were extremely friendly and very attentive.
Oh, this is my first post too. This forum is full of great information
