Delta Air Lines is offering free flights to immediate family members of victims of the Orlando attack.
Atlanta-based Delta said it is also working with funeral homes to waive transportation fees for the deceased.
The airline said customers can donate their frequent flier miles to the American Red Cross through SkyWish, the charitable arm of its SkyMiles program.
Delta also has employees at a family center in Orlando set up at Camping World Stadium (formerly known as the Citrus Bowl), and has set up a dedicated reservations phone number.
Members of Delta's Employee Equality Network participated in a vigil June 14 in Atlanta, and plan to attend a vigil June 19 in Orlando along with members of Delta's Latin American Hispanic Employee Network. Flight attendants are leading a "ribbon campaign."
