Why can’t I modify my trip?

Sometimes, reservations cannot be modified online because the vendor or your company or travel agency has restricted them. 

Some trips or segments cannot be modified online. These include:

• Multi-city flights
• Flights in a multi-city reservation (e.g: multiple hotels or multiple car rentals)
• A flight for which you are already checked in
• Services in a trip that has already started
• Flights with more than one ticket (also called a split ticket), for example, a departure flight with Delta and return flight with United Airlines
• An itinerary that contains an element added by a travel agent (known as passive segment)
• Any flight where the name of the traveler differs from the name in the profile, for example, a company guest is flying but the reservation was made by an admin
• Only the inbound flight is modified
