That is an absolute bargain!

Delta charges:

"Change Fees
Based on the fare rules, you may have to pay a service fee and/or a difference in fare. For travel within the 50 United States, the fee is $150 for Delta flights.

For travel outside the United States, the change fee is typically $250, but can vary based on location and type of fare. Changes are usually permitted only to the return portion of an international itinerary."
