Keith,
I have not flown out of the Lisbon airport so I do not know the airport. It sounds quite chaotic. All of the flights to U.S. are in the morning, latest is 12:20pm. If Serenity arrives Lisbon at 9am, the earliest flight is 2pm (using the 5hr flight recommendation). This means that I have to stay in Lisbon another day and fly out in the morning. I will have my TA call Crystal and verify the arrival time.
Thank you so much for your post.
Pat
