Cheapest Business class fare to Europe

getting really frustrated in trying to find the cheapest way

then continuing on Business to London - that could save you a couple thousand dollars. eg. PER - SGN return = $560 on Jetstar and SGN - BKK - AUH - LHR = $2574 return on Etihad + Vietnam Airlines in Business

Qatar airlines have cheap business class fares from Bali (DPS). For example DPS-LHR is US$4,072.63 return. It is expensive to get to Bali in business class from Perth, although it is very cheap in economy

Don't book your ticket until around mid Feb. That's when the sale fares (including those for business class) get released for the 2nd half of the year. Currently, you'll be looking at the $6500-$7000 mark for your travel dates but wait until next month and you'll probably be able to score a ticket for <$6000. My other suggestion would be to check the various airline websites individually, as they may have great fares which travel agents don't have access to. For example, I'm looking at flights to London (from Sydney) in October and Malaysian are offering $9300 in first class all the way on their website but every travel agent is quoting $15000!
