My preference (and profile) is forward window for domestic and international. I am reasonably lucky insofar as I will usually get seated a few rows behind business if I'm not seated at the front of the bus. However in saying that, an empty seat next to me is well worth the extra wait exiting the aircraft. If I need to sit further back to get an empty seat next to me, so be it therefore I always ask on check in to block the seat next to me off - in most cases except the early flights ex Melbourne (I can't speak for the others) Qantas will do this.
Mondays Singapore to Frankfurt I was allocated 26K (bulkhead), I changed to 27K with 27J empty and 27I another Platinum. All seats in 26 were taken.
I have previously sat 4 rows from the back on a long haul to get "lay down room" across the seats - worth every minute of inconvenience waiting to exit the plane in Frankfurt...
Asile or window - always under debate. I choose window because I like the view, I like playing "what's that city" using Flight Path and some creative thinking (lol) and last but not least, my "squishy" - a horseshoe shaped pillow (not a blow up one) fits well between the seat and the wall with a pillow filling the gap and I can make myself reasonably comfy on long haul. Also, I don't mind asking people to move as I don't mind being asked myself if for some reason I am in the isle.
Happy landings.....
Oh BTW, the stupid posting times are not insominia caused, I'm in Sweden at the moment, getting bloated on over priced 3.5% beer.... hoo hum...
