+ The shuttle service only operates from C to B and stops at B upon request, not B to C
+ The shuttle is operating from Terminal C, Gate 71 to Terminal B.
+ The airside bus takes about 5 minutes, and it runs very frequently, they don’t publish a schedule but I would estimate it runs every 10 minutes.
+ The trip from the Polaris lounge to B gates takes a maximum of 20 minutes.
