Am flying London to Melbourne/Sydney end March in business, and looking to book this weekend. Not sure whether to go with Qantas or Emirates, as have had good experiences with Emirates before, albeit in 2006 and 2009, and have never flown Qantas before. I am travelling with my other half, and usually fly BA and have racked up lots of avios, but wanted to try something new, and fares are pretty good at around £2800. Any advice much appreciated!
