Kevin Smith experienced turbulence on a Southwest Airlines plane yesterday before it ever even left the terminal. The actor/director claims that a pilot kicked him off of the flight from Oakland to Burbank, Calif., because he was too large to fit in a single seat. According to the airline, its customer-of-size policy requires all travelers must be able to put both armrests down or purchase two seats. The 39-year-old, who usually does pay for two seats, opted to squeeze into one because he was flying standby, which lead a flight attendant to request that he vacate the aircraft, immediately. Kevin insists that not only were both of his armrests down in the proper position, but that he also already had his seatbelt buckled. "I'm way fat, but I'm not there just yet," he posted on his Twitter page, shortly after the incident. "I broke no regulation, offered no 'safety risk' (what, was I gonna roll on a fellow passenger?)," he added. The airline has issued an apology to Kevin via Twitter and its website, and also offered him a $100 voucher, but there's no word on whether, Kevin, who arrived in Burbank on a later flight, will ever fly the friendly skies with them again.
