Do I have to collect my checked luggage if I leave Heathrow during a long layover? My agent says the bags are checked through to our final destination, but if we leave the airport, we have to collect them. Is that true? How do the baggage handling service know if we are leaving the airport or not?
No, that's not true. In fact, if your bags are checked through, it's not even possible to collect them since they're going straight to your next plane, not the baggage carousel.
No, You don't have to besides, I even wonder how you can even get them. They are redirected to your final destination and there is no such things as taking your bags out whether you have a short or long layover.hope this helps.
