It is very important to report this before your trip. Be aware that you will not be entitled to a refund after the flight is over. If you have purchased an airline ticket for the same person on two different sites, you must contact the airline immediately. Then you need to request to cancel one of them. Most airlines will get this done without any financial compensation. However, this is certainly considered a mistake and you may have a financial cost.
We will send a request to the airline and get back to you as soon as we receive a response from them. We take all the action from there. If they cancel the reservation without reimbursement to your account or card (depending on how you paid for the airline ticket) you will be refunded.
Except by emailing us, you can always contact us by Instagram or Facebook. However, considering that the mail is an official document, we ask you to use it as the main way of contacting us.
