We typically do not advise our customers book flights until four months out from their trips. Often flights schedules or routes can change if they are booked very far in advance which can lead to frustration and issues with scheduling. In our experience, prices usually remain pretty stable between two and six months with only minor fluctuations.
In addition, we provide a window during which you will need to arrive and depart in order to take advantage of the airport transportation if included in your trip. This window will be sent to you three to four months in advance of your trip.
