I appreciate your flight attendants
What makes you say that?
They always listen and notice my comments and requests
The attendants being kind is a good reason for you to appreciate them. It is good to show your appreciation to those who do nice things for you.
I'm going to send my friends their way.
I am glad for the recommendation. I think that it makes sense that you liked them because they were so kind to you. Thank you for sending your friends too.
