This is my first post on this website,take it easy on me plz:>
As was said before, the last thing needed is an A vs B war...
therefore, when i was departing JNB for SYD in january, on a Qantas B744, the normal flight is non stop to SYD, but the Captain had to make a judgement of either leaving behind 16 passengers and having no problem with reaching SYD, or stopping over to refuel at Perth.He did however choose to refuel at Perth.
Therefore this shows that any little weight, even on the mighty B744 makes an enormous difference, a difference of gettin airborne or not in the current circumstances.
p.s it was relatively hot that day as one would expect in summer.
