John F. Kennedy International Airport (JFK) Terminal 4 is encouraging terminal staff and passengers to celebrate World Smile Day on October 4 with a social media campaign on Instagram and Twitter.
This Thursday, terminal workers and travelers will be encouraged to take photos of their smiles and post them using the hashtag #T4SMILE. The pictures will be then be converted into photo stickers which will be hand-placed on a wall, creating a beautiful mosaic of smiling faces.
