Here’s a feature that would’ve been a lot more useful before this week. Amid recent hours-long airport lines, United is adding security wait times to its app. However, the feature arrives a few days after security lines began returning to normal. Hey, at least it’ll be there for the next shutdown.

At launch, the feature is only available for United’s hub airports. That includes Chicago O’Hare, Denver, Houston, LAX, Newark, San Francisco and Washington Dulles. Passengers traveling through any of those locations will find the feature in the Travel section of the United app. It will display separate wait times for standard security and TSA PreCheck lines.

However, timing is everything, and that’s where United comes up short. This week, airport security lines finally returned to normal as TSA workers began receiving their first paychecks in over a month. Go figure: That led to better attendance and, therefore, short wait times.

Over 60,000 TSA employees had been working without pay since the partial government shutdown began in February. The DHS shutdown continues, but President Trump belatedly ordered the agency on Friday to begin processing back pay for TSA employees. When asked why he hadn’t signed the order much earlier, White House spokesperson Karoline Leavitt cited an “existential crisis” at airports. (Translation: It contributed to an existential polling crisis for the president.)
