Air Hag - well said !!
There was a company that operates into Australia during summer called Airtours.
They flew London - Bahrain - Singapore - Sydney.
They managed to squeeze over 290 pax into an all economy B767-300 ER and catered primarily to backpackers on this run.
Like an old family friend that served on submarines during WW2 said, "the ship stank of ar$eholes and armpits" - but nothing compared to 290 in a similar sized tube !!!
