There are different types of airlines, for example low-cost carriers. If you have booked a flight with a low-cost carrier like Ryanair, Wizzair or Easyjet we can't access your booking or answer any questions regarding your booking because they use a separate booking system that we have no access to. 

For any changes or cancellations, please contact the low-cost carrier directly. You'll find your booking reference and the low-cost carrier’s contact information in your confirmation from them or directly on the airline’s website.
