This website is meant for United Airlines' customers, because it provides useful services but doesn't talk about the company itself. In this site you can confirm your flight status, itineraries and schedules, just by entering your flight's number. You may also check out flight availabilities in any particular date and time, from any place to another. If you're a member of the Mileage Plus, you can watch your summary just by entering your personal number and zip code. In this site you can also find the way to contact some of the UA departments: United Reservations, Award Reservations, Mileage Plus, Support, Baggage service, and customer's relations. So, if you have any doubt about your UA flight, just visit this site.
