Washington, Feb 26 (RHC)--Several US companies, including Delta and United Airlines Are joining a list of US companies cutting ties with the National Rifle Association (NRA) after the February 14 massacre in a high school in Parkland, Florida.

The carnage of 17 people was conducted by a former student with a legally purchased AR-5.

Gun-control activists are organizing boycotts of companies with ties to NRA and people on social media are calling for punishment of companies that offer or have offered special deals to NRA members who, as part of their membership, receive discounts on things like car rentals and prescription drugs.

Delta was offering flight discounts to the NRA´s annual convention in Dallas in May and on Saturday it discontinued the discounts and asked the NRA to remove the information about the perk from the convention website. United Airlines issued a similar statement a few hours later.

Other companies that have ended partnerships with the gun lobby include the global insurance company Metlife, the First National Bank of Omaha, several car rental giants like Hertz, Avis and Budget, and the cybersecurity company Symantec.

Over the week-end the on line effort under the #BoycottNRA hashtag also focused on tech giants that stream NRA-produced videos like Amazon, Apple, Google and Roku and a petition demanding that Amazon drop NRATV channel had gathered more than 100,000 signatures.
