I highly doubt that they are still in Greece. The permit from the Greek ministry of culture specified that they would film in locations of historical importance at the 28th and the 29th of September. I haven't found another permit and it's difficult in Greece to not include even one historical place.
They arrived in Greece at the 26th, they had two days of preparations (27-28) and they run the leg on the 29th of September. The plane departed for Lisbon on the 30th.
If the pattern holds true then they arrive in Lisbon, have two days of preparation and they run the leg on the third day (that's either today or tomorrow). I would expect to see movement from the plane in the next couple days
