Has anyone exceeded the 50lb per checked item limit on Song? We're flying out of Newark. I've *never* been charged for an overweight bag from Newark or Orlando. They just slap a "heavy" tag on the suitcase and I'm on my way. I've heard on other sites that Song is being strict with overweight checked baggage, but I don't know if it applies to Newark or Orlando. Has anyone had success/failure from either airport?
