If you mean 13th of March by saying "13th" and you bought an LHR-IST ticket on BA and a ISL-ASB ticket on TK for tomorrow. Good luck with that. 4 hours may not be enough.
Sorry, yes its 13th April
That's good to know there is no partial move - Turkish are saying so many things about "WE are moving that day", they don't mention the whole airport operations.
