My worst airport is Atlanta. Best? Tampa airport.
I’ve flown into St. Maarten. Wasn’t scary at all.
I spoke almost ZERO Portuguese, but a man in the seat next to me explained what was going on. When we got to Sao Paolo, I found someone who worked there, who spoke some English, and the airport ticket booths were nearly empty, I got taxi voucher for hotel, and free hotel for the night, because next flight out was the next day.
I thought the people in the Sao Paolo airport who took care of my needs were GREAT. It was kinda scary being a woman alone in a city of 23K people. My friends were on a different flight from Salvador to Sao Paolo and by the time they arrived at S P I had my taxi voucher and hotel reservation in hand. It was an experience! But it ended well.
