yeah they check for each and every day. Irrespective of warnings. If prime you need to maintain 1L MAB. I maintained above 50k but less than 1L for 1 week. They didnt award prime rewards. and whats worse is they dont even give infinity rewards( fr maintaining 50k MAB). All they say is the reward...
Lounge access update based on my personal experience. I used my primary card for accessing lounge last week. This week used my wife's addon card fro accessing lounge. So lounge access is separate for primary and addon. Once per quarter each.
yes its very much painful process. they will send the pin through sms. You dont have a choice the set pin for add on card except for the first time during its activation.
I have kept 25 k for 3 months and the fee got reverse sometime in 4th month. I got the banner while applying that special offer of 25k MAB for fee waiver. If that banner is showing up even now then the offer should hold good.
