HI, I have tried three times now to get in touch with United about a simple upgrade for Friday. How can the company make any money if people can't reach them? Or is it just me? Maybe I am calling the wrong number? Does anyone know a number to reach United that gets through in less than 30 minutes? Also, I am trying to do the upgrade online but it won't let me click on the seats for the p.s. flight for some reason. I tried both safari and firefox browsers. thanks, Vince J.
