How does it work?

  • After you have booked your flight on this website, you will be invited to make an offer to upgrade to a higher class, from your booking confirmation page and confirmation e-mail.

  • If you didn't book your flight via our website, you'll be able to place your offer in Manage my flight. All you have to do is to name your price to upgrade each leg of your flight and follow the simple steps to confirm your offer.

  • You can modify or cancel an offer up to 72 hours prior to your flight's scheduled departure in Manage my flight.

  • 72 hours prior to departure, we'll notify you via mail if your request for an upgrade had been approved or not.

    • If your upgrade offer has been accepted, your credit card will be billed with the amount you offered. When you check in for your flight, you will receive your upgraded boarding pass.
    • If your upgrade offer hasn't been accepted, you pay nothing and keep your original ticket.
