It was the first flight for the young captain and he did a great job! Also kudos to the flight crew for getting the passengers to let him know how he did.

Cons: Sarasota ticketing agent was not very nice at all 😟 Houston Gate agent was not nice either. We were treated like we were stupid for asking questions. I hope it’s not racism issues. I wished I had taken their names.
