Some time ago I was boarding an Easyjet flight (when they didn't allocate seats), pretty much at the head of the queue after loading those with kids or reduced mobility was completed. I was heading for the over wing exit row for the extra leg room (I'm comfortably over 6ft tall), when I noticed a mum with kids (all short) heading for that row. However, my dismay turned to relief when the steward refused to let them sit in this row - ostensibly because they patently wouldn't be able to operate the emergency door. However, I like to think there was an element of the steward thinking 'you're all 5'4" or less, what on earth makes you think you need extra leg room seats?' - but I don't imagine that was uppermost in her mind.
