Issues with DL.dumb advertising mileage rates and never letting me book. Told 28 minutes last night, callback was just over an hour. Trying again tonight. Told 50 minutes; we're at an hour and a half. Tried Twitter as well, actually got an agent, but she didn't try too hard and gave me a "ME doesn't have a mileage deal (you can earn, not redeem) with DL," to which I told her "then why do I have a return flight on ME using miles?" I'm not sure why I stick with DL or try to save miles for nice things anymore.
