BA Silver requires 600 TP's and 4 eligible flights, or 50 eligible flights. You look to be quite a way off making silver.

BA Silver requires approximately:
9 longhaul economy returns
25 shorthaul economy returns (making 50 eligible flights)
3.5 longhaul premium economy returns
2.5 longhaul business returns.

The BA program makes it much easier to achieve status flying in higher cabins, so if you can upgrade to premium economy or business that will increase your TP earning.
