We spent over 5 hours stuck in a hot plane without food. Then they deplaned us. 10 total hours stuck at the airport. Then 13 stuck at a hotel. I missed a shift that cost me $187 in wages. After almost 5 hours in a Customer Service message thread, Delta offers me a $100 voucher, as if I want to fly with them again. Oh, and they refused to give us SkyMiles for our outbound flight. Over $1000 of flights and 0 miles after all that. And then they refused to send me a copy of the 5 hour message thread. Mechanical issues happen. But they could have made up for it with excellent customer service. Instead, they did the opposite. What a horrible experience.
