PIA - Pakistan International Airlines (PK, Islamabad Quaid-e-Azam Int'l) is trying to develop its existing, albeit limited, one-way codeshare partnership with Turkish Airlines (TK, Istanbul New) so as to continue providing international connectivity in light of the EASA and FAA bans on the Pakistani carrier's in-house operations, the Dawn daily newspaper has reported.

PIA planned to restart operations to Istanbul New in early August, hoping to use the Turkish gateway as a convenient connecting point for its passengers travelling onwards to Europe and the United States, two key regions where PIA cannot currently fly. The Pakistani carrier was banned following a scandal over fake pilot licences.

As a first phase of upgrading the existing code-share partnership, PIA will add its code to services operated by Turkish Airlines from Istanbul New to Birmingham Int'l, London Heathrow, Milan Malpensa, Barcelona El Prat, Copenhagen Kastrup, and Oslo Gardermoen. According to the ch-aviation schedules module, their current codeshare partnership already includes Amsterdam Schiphol and Athens Int'l in Europe.

Turkish Airlines Chief Executive Bilal Aksi wrote to his counterpart at PIA Arshad Malik that the "considering the networks of both airlines, we see that the volume and utilisation of our agreements have been lower than our expectations", but added that the new destinations could bring improvement.

Turkish Airlines said it was tentatively open to expanding the code-share partnership to a two-way deal. Currently, while PIA places its code on Turkish Airlines' routes to Europe and to Karachi Int'l, Islamabad Quaid-e-Azam Int'l, and Lahore Int'l, Turkish Airlines does not place its code on any flights operated by PIA.

In January 2020, PIA announced its plan to enter into a codeshare partnership with Pegasus Airlines (PC, Istanbul Sabiha Gökcen) via Istanbul Sabiha Gökcen, although it has yet to be formalised.
