Like I said, I could give a sheet about the persons comfort level behind me. (within reason) not for some douche who wants to use his laptop. The video ad even portrayed the person installing the device as being able to use the extra space and even recline their seat on top of it. So they get to recline their seat while blocking yours?
Solution. Upgrade to first class or change airlines. Cairns is correct because the cost of ones ticket will be in direct correlation to ones level of comfort and or amenities.
