to explain
Trying to answer this :
If you will work for DHL Air or DHL UK and you are LEJ Base then you will struggle to commute to/from England since you have low priority on jumpseats and because you only have a few days off it can become very stressful. It is possible and many do it but not always easy. Specially over the weekends ( fewer flights ) and now in the winter with all the delays and if you have only 2 or 3 days off you might spend only 24h at home before trying to commute back again.
If you will work for EAT LEJ then you will have the same problem as mentioned above . Only a few days off and not always a free jumpseat to/from UK.
A comment about the block or fix roster ( which is important for commuters )
DHL Air don't have it ( they hope it will come back ) and EAT Lej have it for their existing pilots but not for new joiners anymore.
Hope this helps
