Just completed my first of two trips.
Bonus miles received the moment the 'normal' miles were added to my m&m account, so that's good.
Took a throne outbound which I found horrible, impossible to sleep. Changed my inbound seat to a middle aisle seat which was much, much better. Slept for a solid 5hrs which doesn't happen too often when in a J product.
Service good outbound - food as well, and as a beer aficionado I had nothing to complain about either. The beer of the month was my clear favorite (Bruxellensis from Brasserie de la Senne).
Inbound, mediocre. Crew is friendly but very loud, meal quite simple, no drinks menu or stuff like that.
Have another one in 2 months.
