My seat: 4a (with a spare seat next to it, bliss).
Fellow passengers: A pretty relaxed lot. When the pilot announced he was skirting Iraq, Syria and Ukraine, adding 20 minutes or so to the flight time, I did not hear any complaints.
How full: About half in the parts of the plane I could see.
Entertainment: Wide selection of movies, games and so on. Big screen.
The service: Exemplary.
Food and drink: Good quality and plenty of it.
The toilets: Clean and fresh.
Luggage: Lots of space in the overhead lockers.
The airport experience: KL was busy and efficient. Before boarding we waited in a lounge that had cigarette smoke wafting into it. Yuck. Paris Charles de Gaulle was not too crowded but surprisingly lax with passport controls and no biosecurity checks.
Would I fly again? Yes. Modern planes, friendly service; just what you need on longhaul flights.
