@20345532826 I am aware that Southwest's policy is different than TSA's, but unfortunately for you, Southwest does say they require the 2nd case. I suggest when you have completed your travel you write Southwest and let them know that the policy difference caused problems for you. Use the contact us link at the bottom of this page and send a message. This is a customer to customer forum so no one here can change Southwest policy.
