I would have thought that you would firstly need to get accepted on Airlines scheme, and take the intermediate and advanced parts of the training again.
I have no doubt, it is not as easy as it seems. If I was you, HEJT2015, I would contact the authority you obtained your License with.
It appears you have an Airbus rating, judging by your past comments on here, so I would take a guess that you're looking at a 737 rating, I cannot seem to imagine there being many jobs on 737's in the next few years for a low hour pilot.
Best of luck
