Typically, there are a certain amount of tickets available at a particular price. Once these are sold out, the next price category becomes available (usually at a slightly higher price). If there is only 1 ticket available at the initial price, the total price can increase when searching for 2 or more people.
On TravelGooru.com, we show you the total price for all travelers. Once you have been redirected to the online travel agency or airline’s website, you will sometimes be able to see a price overview that specifies the exact price per person. We recommend that you always check the itinerary and conditions carefully before finalizing your booking on the supplier’s site.
