Sama Airlines, a Saudi low-cost carrier, plans to buy 20 aircraft over the next four years from either Boeing or Airbus, its chief commercial officer said on Monday.

Kevin Steele said the privately-held firm would make a decision on the jets by the year-end.

'We are looking at finalising aircraft ... 20 aircraft in four years,' he told reporters on the sidelines of a conference.

Asked which aircraft the carrier might purchase, Steele said the choice was between Airbus' A320 or Boeing's 737-800.

'To survive (as a low cost carrier) you've got to be a 20 to 25 aircraft company,' Steele said. Sama currently has a fleet of seven 737-800.

'We're looking at external financing, all options are being considered,' he said. – Reuters
