My wife and I will be travel from Istanbul to London with a 7 hour layover in Tegel. IST to TXL is on Turkish airline, and TXL to LHR is on Lufthansa, both Star Alliance. Will our checked luggage by checked through direct to Heathrow or would we need to clear customs and recheck them in Tegel? Not sure of interline or non-schengen restrictions.
If we can get out and explore the city, when would we need to return to the airport by (flight is at 6:10)? Assuming the luggage is all worked out, we should already be checked in with just carry-on luggage at that point.
Thanks very much
