Every time this has happened (and the last availability has been pulled) I call KL and ask them to search the flight and my name etc. and they pull up a PNR connected to the incomplete booking and then I can make the payment over the phone. It is worth bearing in mind in case you ever experience this and can’t risk waiting for the availability to (hopefully) be restored. So it seems every time this happens a PNR has been created
in their system but you just can’t see it.
