I agree that in circumstances such as this, Maybe it is a good idea that Airlines send a cancellation notice, (we as yet do not

) if they have your email address on file, but you state in your post that you may have "Inadvertantly cancelled your ticket" but you have no recollection ?!?... Now if I had paid that much money for a ticket, I would be making 100% sure I didn't "inadvertantly cancel it". Airlines are not responsible for the cancellation of tickets unless they cancelled it, If the booking is shown as the passenger cancelling, then thats your choice in their eyes, its not up to the airline to let
you know that
you have cancelled a ticket that
you booked!
Keep everything safe, and if you think for one minute you may have done something online to affect your booking, Call the airline!
Read all terms and conditions carefully, they hold the key to a safe and pleasant flight with no surprises!
