United Airlines has some really low unadvertised fares from their competitor's hub airports. Fares range from $122-$158 before tax and are valid for a 330-day travel period, 7 days a week. However, not every travel day will be available at these amazing fares and summer dates are extremely scarce or not available at all depending on the route. Nevertheless, you can get a great price if you buy now. These fares are unadvertised and will not last very long at all. They could be gone in just a few hours. Tickets require a 7-day advance purchase.
Sample fares include: (Also available in reverse direction)
