AU Flights

Hi just thought ill make a new question.
Ur your will be kindly greatful.

Im going to choose a seat on the plane online for the first time and print the boaridng pass like normal paper A4 since i was told it is real ticket ones its print.

I want the window seat.. perhaps far at the back at least i get to see the views and the inside plane interior..

There will be 3 seats beside me and 3 seats on the right side.. im traveling domestic brisbane to melbourne city australia.

I dont no who will be seating next to me… I want the window seat.. i ahve 24hours before departure in which to print the boarding pass and choose the area u wish to be seated in the plane.
If i was the window seat.. what will the ticket say?
will it show a letter? or a number or will it say Window 35seat on the right plane ?

Now thw big question is this: Who ever the fellow passanger seating next to me seats in the same row as me….
so lets say he or she who ever may be seats in the same row as me.. remember there is 3 seats.. what if the person seats where ever he wants within these 3 seats? he would now which row to go to but he wouldnt no which seat its his so he would prob seat the window or in the middle seat or soemthing… So i cant dispute the eprson if they steal my seat for window .. because if is ay thats my seat… he or she would say how do i know this is your seat…. ? there is no numbers for each seat.. to proof it that you wanted window.. see what i mean? without the proof of this… there is nothing to fight about…..

U just get a ticket saying the location like row 35 and thats where u go on thr right side and seat where ever within the 3 seats… so how dificult is that without knowing this is your actual seat without seen the number of your chair? people would be clueless and they would seat where ever but in the row they go to..

So how will i know i get window? thank you.

I am trying to save financially. For a 35 min flight I find $322. too much to pay to fly RT from FL to Nas Bahamas. Any great deals to get around this please help. For the past 3mths have been searching online with no results.

Thank you
