You can transit, and you can use the lounge. You may want to consider using the plaza premium lounges which are open 24 hours. Also look into the Aerotel but it looks like it’s closed until December.
Is there an announced re-opening date for the Aerotel?
That would allow for a place to sleep airside?
We'll have access to CX premium lounges, but they close for several critical hours.
Thanks.
