I am having Airtel Axis since last 8 months, but never got LE offer on it. Use is somewhat 30-40% per cycle of 15k limit.
Prior to that had Flipkart Axis, barely used, had received LE in less than 6 months from 15k to 65k, but I forgot to transfer/club Limit for both cards before closing FK Axis.
Now having Ace with 30k limit, hope to get LE on it soon.
