Expedia's policy on name changes or corrections varies depending on the specific travel service provider (e.g., airline, hotel, car rental company) associated with your booking. Generally, changes to bookings—including name corrections—are subject to the terms and conditions set by the individual travel providers, which may include fees or restrictions. To determine if a name change or correction is possible for your specific booking, it's essential to review the rules and restrictions provided by the relevant travel provider at the time of booking. You can find these details in your booking confirmation or by contacting the travel provider directly.
