As far as Long Haul is concerned, I fly Business while I can still (though barely) afford it. There will come a point one day (soon) when I will be forced to downgrade to Economy Plus (though only on sectors of maximum 8 hrs mind). With present Y cabins I will give up L/H travel rather than fly Economy. Most Economy cabins have now become intolerable. There does indeed need to be worldwide legislation for a comfortable Economy seat pitch and seat width.
