We were fortunate enough to travel business class on our trip and found that even though the pillows were bigger that it still wasn't big enough for Tommy to lay across when he slept on my lap.(Quite often i cheated and fed him to sleep :-$ ) But it's up to you i guess it saves on hand luggage if you just use the ones they supply. Also i found the business class blankets to still be quite scratchy and we weren't given any sheets so it was either blanket or nothing. So I definitaely recommend you take something of your own. Best of Luck and Enjoy, it's tiring but definately worth it in the end.

P.S the way there always seems to be better than the way home!!!
