[Frustrated in Phoenix]

I paid for two tickets one with miles another with a credit card on Delta going to Rome in September. I even had an agent assist me with checking on seat availability and secured and confirmed all my seats and sent my tickets. Today, my husband received an email from Delta with a new seat assignment way way in the back of the plane. I never got an email. When I went online to see my itinerary sure enough they put me in the back with him. When I called Delta, they said it was an equipment change. Actually it was flight number change, but the equipment was exactly the same and we pulled up the flight online with the agent today. When I questioned why we were moved from seats we were assigned and confirmed, the agent said "they are saved for platinum members". I can not believe we allow the airlines to do this to paying customers. The airlines are getting away with these scams. They allow you to select seats on their site and then with no notice they dump you in a bad seat. This should be illegal - I asked for a comparable seat and did not get it. We need to let everyone know about the airline scams. Spread the word not to fly Delta and let's get some help from the public on putting pressure on Delta and anyone airline that they must honor seats we already paid for. I plan to post this on my Italy blog. It's discrimination and Delta is engaged in discriminating practices.
