Seat reservations can be beneficial in certain situations, such as ensuring that groups can sit together or guaranteeing a specific seat with extra legroom. However, in cases where the train is not crowded or there are plenty of available seats, a reservation may seem unnecessary. Ultimately, the usefulness of a seat reservation depends on individual preferences and circumstances. **

It's always best to check with the transportation company for their specific policies on changing reservations. **

Finally, you can also keep an eye out for empty window seats once you board the plane and ask a flight attendant if you can move to one if it's available. **
