DL's DTW-HND will become the longest A332 flight in the world by duration - QF's LAX-AKL will be slightly longer by distance, though much shorter since they don't fight headwinds even remotely as strong as polar crossings.

Do either of these flights have payload restrictions? I should imagine these may be significant.

Payload-range 332 vs 788
The 332 is really characteristic in that it's max MTOW area (the down-slope curve over 5000nm) goes all the way to 0 payload, so yes over 5000nm you can choose between fuel or payload. Just decide how long you want to go and you fuel accordingly, what is left is payload . Up to about 14 hours you have some usefull payload (subtract 5-8t for a real world cabin + catering first then the rest is payload).

I believe that is because Airbus did not remove fuel tanks from the A330 vs the A340, so the A330 can take a ridiculous amount of fuel and is impossible to dispatch with full tanks. No new build airplane has that configuration, but it makes sense for commonality purposes.
If you have never designed an airplane part before, let the real designers do the work!

The A330-200 does have a centre tank while the -300 does not, but the -200 still doesn't have the same fuel capacity of the A340 109T v 111T.

Not impossible, but you only have about 9000kg of payload available.
The -200 can hold 109T of fuel, but you only need around 70T for a typical 12hr flight. So you are correct in saying the aircraft has too much Fuel capacity .

Quoting bjorn14 (Reply 9): Where did Airbus get the extra 300 nm range on the 333HGW? BTW, can't wait for the 350R to go into service.
IIRC they raised the MTOW from 233t to 238t, that gives you another 5t of fuel. It was not used for payload (max payload was even reduced slightly from 170t to 168t for VW 58) . Now 5t of fuel gives you about an hour extra flying time at cruise speed ie 480nm longer range but you have to calculate the extra induced drag for dragging those extra 5t to 7000nm where you burn them so the net result ends up at 300nm more range.
