sorry, my browser flipped out. KC, as my attorney, has approval to speak for me in my absence.
ok:
yes, i said that. CLT is a breeze - we flew through immigration, customs & TSA quickly. it is easy to get around in and has long been our fave hub.
BUT 50 minutes isn't much time - esp when they start boarding like 25 minutes b4 flight time. we flew a weekday at odd times, so i can't guarantee it is like that 100% of the time.
so while it may be doable, i cant recommend you try it - it sure is cutting it close. if your inbound flight is even 10 minutes delayed, you miss the connection.
as always, JMO. good luck!!!
