I'm Chinese citizen, leaving in Italy and in possession of an unlimited permission of stay in Italy, I flow from MILAN to BEIJING via LONDON with return ticket, everything = OK,
by getting to the BEIJING airport for the return flight via LONDON to MILAN I have got the check-in refused becouse of laps of TRANSIT VISA for LONDON
Can you pls. confirm that I'm exempted from transit visa,
Thanks & Regards
