Heading for Pubcon and currently in the process of booking the airplane. The booking sites give me several options which because of my international depature all have at least one intermediate stop at an international airport in the US. Stop times vary anything between 30 minutes and several hours. It has been more than ten years ago since my last visit to the US and things have changed quite a lot since then. I therefore don't know which option to choose.
How many time do you currently need on an US airport for the whole process of immigration procedure, getting to the new gate and security checks? 30 minutes seems to less to me, but what would be a realistic time?
