Not every passenger is a spotter and while I dont know anything about
LAX, in quite a few airports in the night there is precious little you can see from some gates .
Also as a few people have already said, dont assume English is understood by everybody. The last Qatar Airways flight I took from my hometown, about 50% of the pax had no way of understanding any of the inflight announcements as they were not familiar with any of the languages spoken.
A first time flier , on a long haul flight can find the situation un nerving, esp with a large number of fellow passengers in wide bodies.

Inexperienced flyer or not, she should have heard, "QANTAS FLIGHT XXX WITH NONSTOP SERVICE
TO MELBOURNE
IS NOW BOARDING."

Not much use if she is a non english speaker and having reached the gate early sees virtually every other passenger getting up to board! (and a
LAX MEL QF flight is very very unlikely to have an announcement in Mandarin!).
And if the flight was light, it is very likely thee would be no one sitting next to her as well.
So dont jump to blame the poor passenger. Alll the passengers are not street smart as you are and enough and more has bveen written about passengers who are nevrous flyers.
And these type of mistakes do happen. Two weeks back, I witnessed one elderly gentleman pulled out of bus I was in waiting to be taken to the Fly Be aircraft to
GLA at
BHX airport. The gentleman was a pax to
EDI boarding from the next gate and the gate agent didnt spot the mistake initially but spotted it before the bus left for the aircraft.
So go easy on blaming the poor pax. Not every one can afford to jet set around the world and in some part of the world the flights are much more expensive than bus fares as well with the result that flying is still a unfamiliar luxury to quite a few.
Cheers.
