Pop singing star Beyonce Knowles has no problem flying economy class, as long as she has some breathing space. Beyonce who is married to rapper Jay-Z, has amassed a multi-million dollar fortune at the young age of 27. But Knowles is admitting she is no stranger to no-frills flights and claims her only trouble is surviving the journey unnoticed. She says, "Even now I sometimes fly economy if I need to. We had a storm in Miami and there was a hurricane coming so we just got out."She adds, "You know the airlines where if you're fifth in line, you sit in seat five? And then they throw a peanut at you with your drink? I don't care about those kind of things. It's just that people don't give me peace, that's the hardest thing."
