Any flight that goes to and from a “box station” (aka no catering facilities ) gets double catered at the hub with the cold boxed meals. Pretty pathetic if you ask me since DL would always double cater plated meals pre-COVID out of hubs to outstations with no catering but I guess this is the new DL experience along with being cheap in PS and serving the new “enhanced” entrees in Y style cardboard bowls.
