Adding another traveler to your journey is an exciting prospect! However, it's important to note that adding an additional passenger to an existing order isn't possible due to the way airline bookings work. Each ticket is associated with a specific reservation, and airlines don't allow for modifications like adding new passengers to existing ones.
Now, about keeping everyone in the loop, your best course of action is to place a new order for the additional passenger. We recommend doing this as quickly as possible, as flight fares are subject to change and often rise as the departure date approaches.
While it may seem like an extra step to make a new booking for an additional passenger, doing so ensures that all travel details are accurately captured and each traveler has their own unique reservation. And remember, acting quickly is key to securing the most favorable fares and availability.
