Austrian-Lauda
I hope you have a pleasant trip
I flew a Austrian /Lauda triple seven to Sydney 18 months ago. OS A321 LHR-VIE and then the 777 VIA -SYD one of the best trips I have made and I have done a fair number. Transit in VIE was off one plane to find the 777 at the next gate.
Admitttedly it was J class ( special occasion for Mrs PB ) but the service was absolutely outstanding-excellent innovative food and great service. Flight also arrived at an odd off peak time for Sydney so breezed through formalities.
I did chat to a few Y class pax as I was so impressed with their J class ( and I have flown this route on BA SQ Malaysian and QF plus a few others) and they all seemed happy- esp about food and entertainment.
Have a great trip

As an aside the uniforms of the Lauda crew were very modern and stylish - the OS ladies while charming wore all red ( well I cannot vouch for the undies) but every visible item including shoes is bright red - striking but not flattering . That said tho they did a first rate job on the short hop to VIE
