Celebrating the fifth anniversary of its operations, low-cost carrier Air Arabia will fly all passengers on all its routes free on October 28. The airline announced on Monday that passengers travelling on October 28 to any destination on the airline's network will be entitled to a full credit of the fare and surcharges paid. The offer, however, excludes the government and airport taxes, which are to be borne by the passengers. The offer is valid for all passengers who book their flights for Oct 28 from Monday. Those who had booked flights for that day will get their money refunded.
