You may have been wondering whether airlines were able to handle the additional checked bags that were a result of the new security rules put in place in August. (or you may not have been wondering, I don’t know). Either way, it turns out that the airlines couldn’t handle the increase very well. August saw a more than 20% jump in lost bags, from 6.5 per 1,000 checked bags in July, to 8.08 in August. JetBlue and Northwest had the best record, while US Airways had the worst, with 10.33 bags lost per 1,000 (yes, that means they lost 1% of all bags checked, a pathetic record).
