Graeme and Cynthia Landels were unable to hide their excitement at seeing their son and grandchildren for the first time in three years.
Mrs Landels said it was the first time she and her husband would spend Christmas with their 3-year-old grandson, Adam.
Their son, Alistair, and his family arrived from Sweden on Monday.
Mrs Landels said Adam and his 15-year-old brother, Mikael, would be tired but excited after their flight.
