To my knowledge J2 does not publish delay information or its despatch rate.
If any other airline publishes their delay information perhaps you would let us know.
In the meantime here are some CAA published statistics on complaints on cancelled and delayed flights for four airlines that have ATOL cover for their flights and which are comparable in their commercial activities during the period of 1 January 2014 and 30 September 2014.
The statistics offered by the CAA, as shown below, clearly demonstrate that JET2 may have the older fleet but also have less complaints concerning delays and cancellations than any of the other comparable airlines and by an enormous margin. Taking only the complaints for delays, JET2 should be congratulated for its excellent record in comparison with the other three airlines:
