Actress-musician Leisha Hailey and her girlfriend Camila Grey say they were booted from a Southwest Airlines flight over a “modest kiss.”

The women were removed from their flight after several passengers complained that their behavior was “excessive,” the airline said in a statement.

Hailey, who is best known for playing Alice Pieszecki on Showtime's groundbreaking lesbian drama The L Word, and Grey form the duo Uh Huh Her. They released a statement through their band denying the airline's allegations.

“In no way were our actions on Southwest Airlines excessive, inappropriate or vulgar,” the statement read. “We want to make it clear we were not making out or creating any kind of spectacle of ourselves, it was one, modest kiss. We are responsible adult women who walk through the world with dignity. We were on the airplane less than 5 minutes when all was said and done. We take full responsibility for getting verbally upset with the flight attendant after being told it was a 'family airline.' We were never told the reason the flight attendant approached us, we were only scolded that we 'needed to be aware that Southwest Airlines was a family oriented airline.'”

In a statement to CNN, Southwest Airlines said the women were removed for their “aggressive reaction” and insisted the airline does not discriminate against gay people.

“We do not tolerate discrimination against anyone for any reason,” the statement read. “In this situation, their removal was directly and solely related to the escalated conversation that developed onboard the aircraft.”

Southwest's “tenets of inclusion and celebration of diversity among our customers and employees – including those in the LGBT communities – anchor our culture of mutual respect and following the Golden Rule. … ALL are valued and welcome.”

Hailey and Grey, however, refuted the airline's version of events.

“No matter how quietly homophobia is whispered, it doesn't make it any less loud. You can't whisper hate,” they said. “We find it very disturbing that the same airline who lauds itself as being LGBT friendly has twisted an upsetting incident that happened into our behavior being 'too excessive.'”

The women added they were in the process of filing a formal complaint with the airline.
