So true Sandblasted.
A while back, 4 years ago, we did a go around 31R with twenty kts on the tail in the A340-500, the missed approach stopped at 2000 by ATC and twenty frequency changes, and ATC told all stations runway changing 04R+04L (now 20kts accross) and we will have you Etihad back in no time, number 17 for return.
3,5 tons gone and back in on 04L, but those were the days of 5% contingency and the another extra 3 tons for whatever reason for the 16:04 blocktime
That being said, we still felt guilty with all the extra fuel remaining, but landing with less than 30 minutes and no emergency declared is the problem.
