It appears both flights use Terminal 1, usually B gates, and that this is just an airside transfer with a quick security check and no immigration. How long is the average transfer time? My concern is that the Condor flight often arrives 30+ minutes late, so I would love to know estimated real cutoff time so I can prepare before landing. It also appears Singapore only closes the gate 15 minutes before departure, at 8:20 AM, which would mean that even if Condor is 30 minutes late, I could still make it without having to sprint like a lunatic? Quick math shows 30 min late → ~40 min to gate close; 45 min late → ~25 min; 1 hr late → ~10 min (includes a 10-min deplaning buffer). THANK YOU!
