1. Many people now carry enormous "carry on" luggage to avoid paying for hold luggage, happily encouraged by people like Mike OŽL.
2. Due to this many pax eg in row 5 are forced to stow their bags in overheads above rows further back, rows 8,9 10 or worse.
The fun starts in an emergency when said "morons" try to push their way back against the flow to retrieve their bags.
Please may I never be there to see it.
