First post, thanks everyone!

I am flying SFO to HAN on SQ business class. They fly a 777-300ER through Seoul to get me there. I really wanted to fly A380 business class, which is only LAX-NRT.

I am considering flying down to LAX to get on the 380, which will cost be about $80. All other costs are the same. Is it worth it to get on the 380 or is the product basically the same?

THANKS!
