ABC News reports that the pilot raised concerns prior to landing that some of the passengers were coughing and experiencing high temperatures.
Food poisoning is suspected as a cause.
But Mr Phillips said that some of the passengers had originally come from the Saudi Arabian city of Mecca, which was currently experiencing a flu outbreak, and that this was also being considered as a possible cause.
