Flights full of women are marking their way to Washington, D.C. for the Women's March on Washington.

On social media Friday, many people tweeted photos of airplanes predominantly filled with women on their way to D.C. The Women's March, which was planned to demonstrate solidarity following the election of Donald Trump, will take place on Saturday in D.C., and sister marches are planned for all 50 states and in 32 countries around the world.

"90% of flight headed to #WomensMarchOnWashington," Andrea Addario ​tweeted with the hashtag #PlaneFullOfNastyWomen.

On Thursday night, a Southwest flight appeared to turn it's cabin lights pink in a show of support with women on their way to the march.

"Southwest turns on the pink lights, and a loud cheer erupts. #WomensMarch" Twitter user Jennifer Moran said with a photo of the pink cabin lights.

Southwest Airlines told Mashable that airline officials weren't aware of the specifics of the flight, but said it wasn't uncommon for flight crews to change the light colors.

"Flight crews celebrate, commemorate, acknowledge and share in special moments with our customers all the time," Southwest Airlines said in a statement. "Some of our aircraft are equipped with mood lighting, and while this was not a companywide initiative, at times, our flight crews will adjust the lighting for a customer or group of customers traveling on their flight."

On Friday, social media photos showed many women wearing pink 'p***Y hats' as part of a national effort to flood the nation's capital with women wearing pink cat-ear hats.

More than 200,000 people are expected to attend the march, according to the march's Facebook page.
