Not that I use QF internationally any more, but this marriage between the two airlines raises alerts.
I flew Emirates all the way MEL - DUB & back recently; while the modern planes and in-flight service were great, I was not impressed by Emirates information, services or its home airport DXB. DXB large & modern like SIN, but directions not so clear and info. desks scarce; I could not find a lounge to rest over & shower during a 6hr stopover on the way back and had to use a rip-off hotel within the airport, though I'm happy to concede I might have done a bit more research on-line when booking. However I'm comparing with similar , more favourable, experiences in KUL & SIN.
Also Emirates airport services a bit chaotic - had to get a boarding pass printed during short change-over at SIN on the way back (DXB - MEL via SIN) - they wouldn't print the pass in DXB where I had plenty of time, and presumably where their head office is!
The 'marriage' may give you more of the 'Emirates experience' and DXB than you really want. Personally I'm going to avoid DXB in the future, however if you are going to transit there, I suggest:
- get all boarding passes printed at the start of the flight if possible
- research airport lounges when you book, if you want a shower or a kip - I think there's good discussions elsewhere in here about DXB facilities.
Other info: I earned 9000 points each way on Emirates between MEL <-> DUB. Hopefully I can soon redeem this paltry amount on an internal QF flight.
