Delta and United airlines grabbed headlines over the weekend as they joined a wave of companies cutting ties with the National Rifle Association.

But North Texas’ major airlines -- American and Southwest -- were mostly absent from the discussion, largely because they have no relationships with the gun-rights advocacy group. The NRA has been the target of a growing boycott movement in the wake of the Feb. 14 school shooting in Parkland, Fla., that left 17 dead.

“To clarify questions we have received today: American does not offer discounted group travel rates to the the NRA,” the company said on Twitter Saturday afternoon.

A Southwest spokeswoman also said Saturday the company does "not have an affiliation" with the NRA in a response to a customer query on Southwest's community website.

Delta and United both sent out statements on social media early Saturday that they were ending group travel discounts for NRA members. The carriers also requested that their information be removed from the group’s website.

More than a dozen other companies, including rental car providers like Hertz, insurer MetLife and home security company SimpliSafe, have announced they were ending similar discount programs over the past several days.

The NRA has called the corporate actions a “shameful display of political and civic cowardice.”

“In time, these brands will be replaced by others who recognize that patriotism and determined commitment to constitutional freedoms are characteristics of a marketplace they very much want to serve,” the NRA statement said.
