When flying Transatlantic flights and using Routefinder, you need to specify that you want NATS to be included in the flightplan, otherwise it will only give you fixes located on or around coaslines, makiing the flightplan much longer than it should be.
It's a drop-down menu, next to the SID/STAR cycle selection box.
I do remember seeing your routing on the live flights display and thinking "where the **** is he going??", and I knew exactly what the problem was. I was also wondering how on earth you were managing to fly that routing, in a 737

I must add that I'm rather surprised to find out that a flight can be accepted by FSACARS, with unlimited fuel being used. It doesn't seem very fair, especially to pilots who put quite some thought into loading the right fuel amount (such as myself). It takes me easily 15-20 minutes of planning a flight before even programming the FMC, let alone starting the engines
