This question already has an answer here:
I'm flying to Lubbock in Texas in September. I can get flights with a 2 hour 25 min layover in Newark, or a 3 hour layover in Chicago.
However, from there I have to get a connecting flight to Houston. The most I can find is a 50 minute layover there before boarding the flight to Lubbock. Will I have to go through customs at Houston as well?
If so, I guess I'll need a longer layover there?
