Links back to my thread for my SIN-MEX connection

Since it's a different topic altogether from my previous thread about connecting between SIN and MEX, I'd be starting a new thread instead (unless decided otherwise by a moderator)

Would like to ask which is the best A380 product to fly on in Economy, out of these 4 airlines? This would be my first leg out from SIN before connecting to MEX
- Qantas (codeshare with British Airways)
- Air France
- Lufthansa
- Singapore Airlines
