Once the MX goes more than a few hours, it need to slip 12 hours to prevent arriving in the middle of the night.
Hard to believe a window replacement can not be done in 12 hours
I just noticed I got the first text message around midnight local time: "your flight has been FURTHER delayed". So I guess there must have been something going on. Looks like one of the flights yesterday got canceled as well.
