United Airlines accidentally gave tickets away online for free on Thursday. The airline says the tickets will be honored.
People snapped up the tickets on Thursday after fares were mistakenly listed at $0.00.

Some customers got their tickets for only the the Sept.11th security fee of $5.00 to $10.00.
This has happened before. Decisions whether or not to honor the tickets are generally made on a case-by-case basis.
United hasn't said how many tickets were mistakenly given away. The error was on the airline's website for several hours on Thursday before  bookings were shut down to correct the problem.
