Air India Flying Returns miles expire end of the month, 3 years after they are earned. However, Air India gives people an opportunity to renew their miles for use as well. Back in the day, I had my Air India miles expire and I was able to get them renewed at INR .10 per mile by going at the Air India office.
However, AI raised the prices of renewal of miles to INR 0.6 in 2015. Last year, in December, they launched a limited time promotion for the whole of 2018, where members could renew their miles for a period of 3 months at INR 0.3 per mile, during the month of their birth. They also made it easier for people to be able to renew their miles on the phone.
Now, there is a new promotion that they have launched only through June 10, 2018, where members will be able to renew their miles at a discounted rate of INR 0.3 per mile on the phone by June 10.
Under the new promotion, you need to call Air India through the rest of this weekend and renew your miles, complete the payment for these miles and you could use them for the next 3 months all over again. It helps if you have a trip coming up and you know you are short on miles, you could use the Air India promotion to renew them.
Remember, you need to have a verified account with Air India before you can go for this step.
It is a good idea to renew your miles if you know you would be able to redeem them in the next 3 months. Otherwise, these opportunities will keep coming and you could use one when it fits your timeline of redemption.
