Preparing for a long trip

I am planning to fly to Spain on a business trip and would like to estimate the route from New York to Madrid in advance so that I can calculate my arrival time and expenses correctly.

When I needed to fly to Madrid, I first spent a long time searching for information on various websites, which took a lot of time. Then I found a description of the route New York to Madrid, which briefly explains how long the journey takes and what the main flight options are. This helped me to plan my trip better and avoid unnecessary worries before departure.
