Check in deadline for int'l flights is T-60.
Are they certain to close a flight at T-29 when a connecting passenger has landed 10 minutes before? No, they might wait a few minutes. Or they might not. Depends on a bunch of stuff.
I've seen a connecting family of 5 turned away at T-25 because they had already processed Y standbys and no more seats. I've also seen them hold a Global First seat till T-10 before filling it with a standby and gate agent followed them down the jetway and closed the aircraft door.
The point is any time after T-30 you are gambling, and a D-I connection has 15 minutes less of wiggle room than D-D.
