Are the gates close to eachother or do you have to get on a shuttle to get to some gates? I don't have much time between flights and need to make sure I can make it to my connecting flight in time. Thank you

The gates don't have a shuttle, there are auto walk ways...it's going to depend on preparing and timing.

I have a 50mins layover. Do u think that is enough time to get from one gate to the other? I know some airports you sometimes have to travel to a different building to catch your next flight. Is it all one building?

Defends on timing & crowds

It depends.
