Sounds like you both had a great vacation. Am glad you weren't stranded at any of the airports like I had seen on the news.
I'm sorry they made you put her back in her carrier. Was she hidden under your coat on the way back? How did they know she was not in her carrier?
I think it all depends on the flight attendents. Some will not say a word as long as the dog is tiny and being quiet.
Welcome back.
