Why shouldn't pre-boards be treated the same way as handicapped parkers are handled? No doctor issued blue handicapped placard..... no preboard! Should be the same. Many many pre-boards are perfectly fine, walk to the gate, then ask for a blue preboard sleeve and a wheelchair to make it look more legitimate. Why do the airlines HAVE to give a pre-board a blue sleeve, without proof, yet you cannot park in a handicapped parking space without a doctor issue handicapped placard. REDICULOUS!!!!! A lot of these folks simply buy the cheapest "wanna get away" fares, then don't like their "C" seating assignment and then get moved ahead of those of us that pay the extra $$$$$ for business select seating. How is this fair??????
