Just a heads up for BA and oneworld flyers.
The JFK Airtrain is not currently operating between terminals. Fed Circle to/from Jamaica is running (and no charge).
The lady I spoke to reckoned its back up sometime Monday.

A weird replacement bus system is in force. It looks a real pain to go T8 to T7, so those on that transfer may need to allow extra time and plan alternative means of getting to T7.

I was into T8 this morning and heading into town; so a scrum for the Group 2 replacement bus at T8 to Fed Circle, then the Airtrain, and finally LIRR as per normal.
