Delta promises free checked bags but does not deliver

Date: 21 June 2013
Airline: Delta/Alaska Airlines
Flight: 7470

The most disappointing flight I ever had! Before my trip, I called Delta SkyMiles representatives to ask whether I could get a free check-in bag with the Delta Gold credit card. The representative said yes, and encouraged my family to carry bags for free check-in. I gave her my confirmation number and she said my itinerary was eligible for this offer. All the flights on my itinerary had Delta flight numbers.

Then, on my way back, I had Delta flight number, but it was operated by Alaska Air. Then Alaska said I had to pay for check-in bags! This is totally different from what Delta SkyMiles told me. After I came back, I called Delta customer care and asked for refund, they refused to take the responsibility of telling me the wrong information!!! I couldn't believe it.
