Hello, Based on my experience, the delta miles calculator (https://rightcheckin.com/blog/delta-miles-calculator-know-the-worth-of-your-skymiles/) was very useful for estimating the number of miles I could earn during my trip. Prior to making my reservation, I utilized it, and it provided a clear perspective based on distance, fare class, and my SkyMiles status. It helped me avoid guessing and improved my planning. I appreciated its ease of use—simply input the route and details. All in all, the Delta miles calculator helped make my travel planning smoother and more rewarding.
