The first A321 batch is due for return to lessor about half of them. The newer half will be transferred to 2P.
The original plan was to give it to 2P but changed midway in 2016 after 29 of their domestic flights were cancelled by NAIA apparently for operating without approved slots.
In 2014, the government was supposed to build either Terminal 5 or Terminal 2 annex that would provide them the slots. Remember that?
None of that plan happened. In 2016, decision was made to have it funded by PPP. None of that happen either. In fact, it is still not happening now. By the time the new Terminal comes in 2023, the earlier A321s would be too old.
