While Southwest Airlines has already begun using new secondary flight deck barriers to reinforce cockpit security, United Airlines has told employees that this security device will not be used until next year on United aircraft.
Reminder: Do not use the secondary barrier Types 2 and 3 until further advised in early 2026. These are found on some newly delivered B737, B787, and A321neo aircraft. Continue to use the full-size galley cart procedures until further notice.
The secondary barriers are a retractable, gate-like device that deploys when the main cockpit door opens (frequent United flyers might recall United used to have these on its Pratt & Whitney 757-200, which were retired in 2020).
A great solo travel tip spotted this week on Live and Let's Fly.
