I rarely disagree with S.O.F. (previously S.O.E. - why the change?) but West bound 747 (etc) freighters would be take off weight restricted at GLA (and EDI). The PIK runway is a national asset. It would be criminal if the vain pursuit of pax traffic caused the whole airport to collapse. As has been said above many times, PIK must play to its strengths and stop believing its future lies with passengers.
