Both companies seem evenly priced and both a notable amount cheaper than all the other airlines.
Similar journey and stop over times.
Where is the better place to have to suffer a period of 6-7 hours? Singapore(SIN) or Kuala Lumpur International?
Singapore use a Boeing 777-300ER for the long flight and an Airbus A330-300 for the slightly shorter flight.
Malaysia use a Airbus 380 for the long flight and an Airbus A330-300 for the slighty shorter flight.
Any notable difference in service or space?
Will be flying economy with both.
