Las Vegas-based Allegiant Air has announced a number of initiatives to help after the mass shooting on the Strip.

Allegiant will arrange for family members of victims for free travel to Las Vegas. If you or your family members need to fly to or from Las Vegas, please write the airline at communications@allegiantair.com.

The airline is also reaccommodating Las Vegas travelers who wish to change their plans this week without change fees.

Allegiant's customer care team is reaching out to customers staying at Mandalay Bay hotel-casino or other hotels in the immediate area of the shooting and reaccommodating to other hotels as needed or desired.

In addition, Allegiant's maintenance staff at McCarran provided shelter and safe space overnight for about 30 individuals who had fled the concert site. They were able to help folks clean up, get them clothes, help them charge phones and make contact with loved ones.

American Airlines is offering change fees to be waived for passengers if they bought their ticket by Oct. 2, scheduled to travel Oct. 2 to 3, can travel between Oct. 2 and 6 and don't change their origin or destination city. If a passenger's trip is eligible for a change, there will be a change trip option in the toolbar. More details can be found here.
