Bally Heck,
Surely you can't be serious, the report clearly states that they were below min-fuel for diversion. I know that they would probably have made it to BCN but as you say they had sufficient fuel is just about as far from the truth as you can get. I would think that if more fuel was carried they/he (commander) wouldn't have been as commited to commence the second approach when they did.
I have to agree with 411A on this one, bloody silly thing to do flying into known adverse weather with only 15mins extra onboard..
