But going the other way (MEL to SIN) is $1.2k in taxes. Ridiculous.
My pet hate, the term taxes! $100 in taxes and $1100 in co-pay. That's what it is, not even a fuel surcharge or anything like that, it's pure and simple a co-pay for award bookings, and Emirates (and Qantas) know people will pay it.
Nesting trips and open jaws help. We've even considered (as living in Singapore) doing a weekend or day trip to KL to save it (SIN-KUL/MEL-SIN has very little co-pay as ticket issued in SIN).
