Free Flight Tickets Were Given out by United Airlines

You ever wanted to have free holidays? 

United Airlines started offering flight tickets at the price of... $0!. Of course this was a mistake that was corrected by the airlines but till that time, several customers had the opportunity to book flights at zero cost.

At the same time, the airline company can not estimate how many free tickets were given out.
The specific tickets were sold last Thursday through its online booking system and what is more, many of them were for destinations such as Hawaii.

However despite the mistake, the company executives decided to let the lucky passengers who had managed to book tickets to travel for free!
