I've found this a number of times and wanted to know if anyone has experience with this, I keep trying to book with my US blue chip number and it doesn't work with Australian bookings (on the australian site) as the US site is more expensive for Australian bookings. are they different companies or does anyone know of a way to do this and possibly earn United miles (which you can't do with the Aussie blue chip.)

thanks in advance
