I definately think you should choose Premium Cabin if you are travelling Longhaul.
Monarch offer an excellent service in their Premium Cabin which includes a greater seat pitch and Seat Back IFE.
You also get a larger baggage allowance and deticated check in at Most Airports but that is never gaurenteed downroute.
On board you have a Seperate Cabin and are welcomed with a Drink and Amenity Kit.
In flight you are treated to an upgraded meal which is of a much higher standard that in Main Cabin. You will also have complementary drinks throughout the flight and a greater choice of In Flight Entertainment and approximately 8 films to choose from!
I also think the Cabin Crew work extremely hard and offer a High Level of Service on board! Hope this is of some help!
