Hadn't thought about Kettles until this thread
Just experienced a couple of kettles at ONT. Lady in the security line asked the TSA clerk if he knew if she was sitting next to her husband because they had seats 9A and 9B. He actually told her he wasn't sure, but thought seats were lettered ABCD. The lady went on to ask if she was possibly sitting in front of her husband instead of next to him. Being impatient, I told her they were indeed sitting next to each other. Looking at me as if I were lying, she asked the clerk if they should go back to the ticket counter to check. I, again, interjected that she could confirm her seating arrangement at the gate.
I jumped on an Alaska E175 operated by Skywest. I hear the guy in the seat behind me tell his son that we weren't flying Alaska Airlines, but American Airlines.
