Jet lag from Istanbul to London
Flying from Istanbul (GMT+3, UTC+3) to London (GMT+1, UTC+1) crosses 2 time zones, travelling west. Based on this shift, expect mild jet lag with roughly 2 days needed to fully reset your body clock to local time in London.
Direction matters almost as much as the number of hours. Travelling west, as on this route, means staying up later and waking later, which the body generally tolerates better than shifting earlier — so recovery tends to track closer to the raw hour difference. The return trip from London to Istanbul goes the opposite direction and can feel noticeably different even though the hour gap is identical.
To plan around it, check the exact time zone difference between Istanbul and London before you book calls or activities, and see the flight time for Istanbul to London to work out your best arrival window. Landing in the early evening local time and staying awake until a normal bedtime is one of the simplest ways to speed up adjustment on this route.
