I have the Vistara Infinite
1) Got the complimentary ticket after the payment of the Joining fees, the voucher is good for 6 months and you have to create the voucher code within that time. After that the code has the validity of 3 months.
2) The card has been useful, surely. Got the whole fee reversed, the 10k CV bonus for 100k spends was easy to achieve and had great value. The complimentary ticket didn’t came to any use for me. No business class connections from my city. The CV I earned and the Gold status compensated for it though. 6CV/₹200 spent.
Also had EazyDiner 40% upto ₹1000 off.
All an all a more than amazing card for FYF.
