United Airlines announced on Monday that regular-paying flyers are welcome to wear leggings aboard its flights.
The news came just a day after two teenage girls were barred by a gate agent on Sunday from boarding a flight from Denver to Minneapolis because of their attire.
An airline spokesman said that the girls were traveling under an employee travel pass, which includes a dress code.
The move sparked a wave of online criticism against United Airlines. Comedian Sarah Silverman tweeted that she would change her United flight bookings to other airlines for a tour next month because of the leggings issue.
Chicago-based United quickly sought to clarify its stance in a post on its website late Sunday titled, "To our customers ... your leggings are welcome!"
The post also added that employees are "regularly reminded" about its dress code.
One of United's competitors, Delta, wasted no time in having fun with the controversy. They tweeted on Monday: "Flying Delta means comfort. (That means you can wear your leggings.)"
