My brother just called me saying that there is a new US custom procedure in YYZ. He was going YYZ-ORD-HKG by UA this morning. Flight was leaving at 9:40 am and they were not allowed to go into custom until called at 9:00 am. This is completely new to me. That means you only have just barely enough time to clear custom, drop luggage and run to the gate and no time to have a drink in the lounge. Anyone has insight into this? Is this permanent or just for the summer peak period? I went to LAX by AC last Sunday and it wasn't like this.
