Flight was canceled due to hurricane, understandable. Trying to use the website to get a refund was a horror show!!!! No phone number to speak with a person.

Hoping NEVER to 'attempt' to use Breeze Airways again and will NOT recommend them to any of my relatives, friends and/or business associates!!!!
