Hello, From my experience, the [delta miles calculator](https://rightcheckin.com/blog/delta-miles-calculator-know-the-worth-of-your-skymiles/) helped me calculate the number of SkyMiles I required for my trip. It provided a rough estimate based on the route and class, although prices still differed. As I was organizing a domestic flight, the calculator provided a rough estimate that corresponded to what I encountered while booking. It’s not exact, but it assisted me in preparing.
