Extra leg room for people over 6ft on all planes. a section of plane for taller people as anyone over 6 foot struggles to fit in the normal seats they have and do not allow people under 6 foot to pre book the current extra leg room seats. People over 6 foot should not have to pay for extra leg room. They (jetstar at least) have now made their seats with Non Adjustable head rests. Someone like myself at 6"6 cannot fit my knees behind the chair in front,  and cannot rest my head as its the head rest is too low. This makes for a very uncomfortable ride and results in a sore back and neck. Something needs to be done, being tall shouldn't be a disability but you are making it feel that way.
