China Southern's Kangaroo Route combo: Airbus A380 + Boeing 787

China Southern is set to serve up its two newest flagship aircraft on the Sydney-London route from October 27, tempting travellers with both the Airbus A380 and Boeing 787 Dreamliner on each leg of the 23 hour trip.

Provided passengers can overcome any nervousness regarding the trouble-prone Boeing 787, the lure of flying on both aircraft will be another factor in favour of China Southern's 'Canton Route' as it lines up in the ranks of Kangaroo Route contenders.

China Southern's superjumbo will carry 506 passengers in first, business and economy class from China Southern's hub in Guangzhou, with flight CZ326 leaving Sydney at 9.50am to reach Guangzhou at 5.30pm.

After an overnight short stopover in Guangzhou it's time to continue your journey to London on one of China Southern's new Boeing 787s.

The Dreamliner departs Guangzhou at 9.05am (flight CZ303), arriving in London at 3.25pm.

But you'll need to be a bit flexible with your travel schedule.

First of all, the Guangzhou-London Dreamliner service will initially run only five days a week, skipping Mondays and Wednesdays.

And with only 228 seats on the Boeing 787 – some 278 less than the Airbus A380 – there could be a few days between flights in order to snare a seat on the superjumbo.

This is probably a good time to mention the new visa-free transit rules which come into effect from August 1st and let you stay in bustling Guangzhou, or any city in the Guangdong Province – including Shenzhen – for up to 72 hours without a Chinese visa.

When it's time to head home, the London-Sydney flight is a fairly seamless affair.

Catch China Southern's Boeing 787 CZ304 flight out of London at 10.35pm, wheels-down in Guangzhou at 5.35pm – three hours later you're back in the air on the daily A380 service to Sydney (CZ325), which lands at 8.30am.
