Joanne Catherall of synth pop band Human League has been booted out of a Qantas business lounge for wearing Ugg boots. Catherall was waiting for a flight in Melbourne when she was bailed up by one of the airline's staff, told of her breach of their rules and politely ejected from the business lounge. Catherall took to Twitter to vent her anger, asking why the airline considers the boots slippers when no one else in the world does. A Qantas spokeswoman said: "We completely understand that no one likes being declined at the door but we've always had smart casual dress standards for our lounges, which are similar for those in place for most clubs and restaurants. Over the past couple of years we have had clear feedback from lounge members that they wanted these existing guidelines to be applied more rigorously." <br/>
