everything here is correct-- 45 mins would be reasonable- 1 hr better. the recently opened new terminal has 10 gates and it is a little walk. (6-10 mins to get to main terminal) the subway sandwiches restaurant has reliable free wifi. US bound flights do require extra security at gate. Most connections are very easy/straightforward. The recently renovated Copa club is similar to UA clubs.. I hear the new one even has showers. duty free is so so. PTY is a great place to connect to most central america and south america- and there are also a few caribbean flights.
