You didn't say BA carry sparse amounts of holding fuel,but your colleague above seems to be doing so. I'm only going on what has been written here, nothing else.I just don't think his actions are sensible from how he is describing the situation.

Flanker, REALLY
Now really you are being perverse. SPARSE?
In relation to the original example of SIN - LHR in winter (stronger winds from the West for 13 hrs), what we do is reduce the ZFW by shedding staff pax/freight/fare paying pax, in that order, until the AUW = RTOW with (note, WITH) the original flt plan fuel offered by the gnomic computer in ZRH or GVA or wherever the damn thing is. All our plans have en-route alternates, so there is no other descision to make. We CANNOT and most certainly DO NOT further reduce the fuel load by shaving ANYTHING off the normal holding reserves.
With the Roller (Trent - Core) powered 400, this is also usually
Max Structural Wt. (We can still use derated T/O power, but that's another arguement if you want it.)
In other words ...... just what you do in your Fluff-Jet, but with bigger numbers.
Please don't accuse me of carrying SPARSE fuel. Or if you do, shout at the CAA, it's their set of rules.
A lot can happen to an ultra long range flight before we creep onto H109, or whatever they call the edge of your known world. It's FINISHING the flight with sparse fuel that concerns me.
