Possibly enough time for a quick L2 metro from the monorail to see the view from the Bund and Nanjing Rd if you haven't been to Shanghai before.. but all depends on immigration and your risk tolerance.
Agreed with three major airlines effectively grounded empty seats on any other airline are filling up very quickly.
The next genuine earliest opportunity could be a while.
Hope they can operate more than one..
Unfortunately I suspect all other services to the US and Asia have been filled up over recent days so there isn't any ability to combine flights.
Suspect it's more Telstra Wholesale raising prices. Other MVNOs and IoT providers have also had big increases.
Anyhow I renewed my $170 plan a few weeks early so good until Feb 2027.
Youngest - 2014. Oldest at a guess 2007.
But we still don't know when the older 737s (from 2002) will be retired. VXH was recently repainted and VXJ is in TSV now - not suggesting either is leaving anytime soon.
