Usually, airplanes are grounded for mechanical and safety reasons.

This time, United Airlines has temporarily grounded its entire fleet of A321neo airplanes because of an old signage issue.

A U.S. law from 1990 requires the ‘No Smoking’ sign on planes to be operated by the flight crew, but on this particular airplane model, the sign is automatic. 

The airplane is relatively new, but you can imagine the trepidation of some who are probably wondering how old the plane is when that sign comes on. Smoking has been banned on airlines in the United States for the better part of the last 30 years.

In fact, the software keeps the sign lit continuously.

United had requested an exemption from operating the “No Smoking” sign, but that was four years ago and did not cover the A321neo. Of course, planes have been grounded for much more severe issues, but a law is a law.

There are only five such airplanes in United's fleet, and United has requested that they be added to their existing exemption.

"As the FAA noted, this is not a safety of flight issue," a United spokesperson said. "Our five A321neos were briefly out of service on Monday while we worked through this issue with the FAA, resulting in a handful of delays but no cancellations as we swapped that flying to other aircraft types in an effort to minimize disruption for our customers."
