A New York family says they were denied family boarding privileges on a Southwest flight over the weekend because the couple are same-sex partners.

Grant Morse flew from Buffalo to Fort Lauderdale on Saturday with his husband, their three children and the childrens grandmother. But when the group stepped up for family boarding , they were denied, Morse told HuffPost.

A Southwest gate agent told them their entire group couldnt board, though Morse said the agent was initially vague about the reason.

We approached the... family boarding area as we have done many times, Morse told HuffPost. The boarding agent assertively approached and said, This is family boarding. My husband responded, We know, we are a family. She said, Not all can go. This is family boarding.
