Did a 13 half hour flight from Manchester to Singapore Via Munich. First hour was easily dispatched by nosying out the window etc then from the Munich leg i spent time listening to my Ipod, managed to read most of a book and next min i know the sun is rising and we are an hour from Singapore. I find window seats are the best, due to being able to rest your head on the window.
Get a seat as far forward as possible to reduce the noise fatigue. Also, they actively encourage you to walk about a bit (seat belt signs off permitting) And being a twin aisle Aircraft on most Aircrafts, you can stand behind a Row of seats at the back near the toilets.
Most uncomfrotable Aircraft was a 747 – 400 as it was very cramped, however the 777 300 was a very spacious Aircraft with lovely seat pitch, even in cattle class.
Flew Business class tho on the way back from Perth to Singapore and Back to Manchester.
