How does the flying returns expiry work? This is what I see when I login go my account. Does this mean the 3000 miles will expire on 31 Dec 2024 regardless of whether I travel before that or not? Normally airlines extend the expiry date if you travel on the airline prior to the expiry. Is that not the case with Air India?
