Why does my ticket cost more than this morning? Do you practice IP Tracking?

No, Air Caraïbes does not practice IP Tracking!
Some personal data may be collected and stored temporarily and directly by cookies during your use of the www.aircaraibes.com website, but these are only used to facilitate your searches (pre-fill destination fields / geographical area...) and not to influence the price of your ticket. The security of your personal data is a priority for us, and our teams are very vigilant about its use; we do not wish to make use of it without your knowledge and especially not for profit.

In addition, it is technically impossible for aircaraibes.com to modify the prices of tickets sold in relation to your IP address. Fares are set in advance by teams responsible for ensuring that our flights are fully booked (see yield management), and are made available to all resellers in a common database. Each time a buyer (aircaraibes.com, travel agency, comparison sites, etc.) makes a new request, the lowest fare level is automatically proposed. If another passenger were to book the lowest fare, the next customer would be transferred to the next fare level (equivalent price if there is availability at that fare, otherwise higher price). Only the service fees differ from one seller to another; those of the aircaraibes.com site are displayed in clear text at step 3.
For your information, each time you attempt to book on our site, and if you go beyond step 3, the fare is reserved for a few minutes (allowing you to finalize your request). Therefore, if you retry the operation immediately, the fare level displayed may be higher (since the lowest price has been "pre-booked" for a few minutes). You'll have to wait before it's released, at the risk of another buyer being quicker than you.
