I'm a little confused. Here's the scenario:
Taking a cruise to Barcelona, staying a few days
Flying from Barcelona to Warsaw on Norwegian airlines
Flying from Warsaw to Rzeszow (a smaller city in Poland) on LOT airlines (same day)
Then, I do the same thing with the flights on my US bound leg (fly from Rzeszow to Warsaw, Warsaw to home)
My questions are: How much time should I allow between my connecting flights for security or any customs?
Any experience or advice is very welcome!
