This merits a thread of its own, methinks, as we try to get Delta to step up with reasonable compensation for the Comair debacle.

I sent an email to DL customer service, and in three or four sentences asked for compensation for my out-of-pocket expenses relating to having to extend my stay.

Delta's response: shameful. See below. I emailed a reply thanking DL for the response, and indicating that I bought my ticket from DL and expect DL to provide the requested compensation.

Any suggestions on what to do from here?

Dear [Mikey likes it],

Thank you for your e-mail to Delta Air Lines.

We apologize for any inconvenience you may have experienced and
appreciate hearing from you. Comair is one of our Delta Connection
partners, and is also a wholly owned subsidiary of Delta. Comair,
however, operates as a separate company. Since the circumstances you
are requesting compensation for involve Comair's operations, please
direct your request for compensation to:

Customer Relations
Comair Inc.
77 Comair Blvd.
Erlanger, KY 41018

Please accept our apology for the unfavorable impression you received
in this instance. We very much appreciate your Medallion loyalty to
Delta and will always welcome the opportunity to serve you.

Sincerely,
