Add GF to the list of airlines that allow for STPC.

Incidentally, I think that the general IATA rule is that "If a passenger has to wait over 6 hours for an onward connection in IATA areas 2 or 3, you can ask an airline to book a hotel at its own expense". STPC stands for "Stopover Paid By Carrier".

IATA Area 2 consists of all of Europe (including Russian Federation west of the Urals) and adjacent islands, Iceland, the Azores, all of Africa and adjacent islands, Ascension Island, the part of Asia lying west of and including Iran.

IATA Area 3 consists of all of Asia and adjacent islands, except the portion included in Area 2, all of the East Indies, Australia, New Zealand and adjacent islands, the islands of the Pacific Ocean except those included in Area 1.
