Yes, it is often possible to modify a travel booking after it has been confirmed, but the specifics can vary based on the terms and conditions set by TSP Travel. Modifications can include changes to travel dates, destinations, or passenger details. However, there may be fees associated with making such changes, and availability can depend on various factors, including the type of fare originally purchased. It is also essential to be aware that certain bookings, such as non-refundable tickets, may have more restrictions and may not allow for changes at all. Due to these factors, it is advisable to review the terms of the booking you made.
