Having used Crossover Rewards, I've immediately alerted Delta Airlines that someone has access to my Delta SkyMiles number and enough personal details for identity theft over the phone or email communication.
I've requested assistance in securing my account further or having a new membership number issued.
You can send in your own request to see if you've had details leaked in the data breach through this form.
