I am ganesh gatwari, age 69 & travelled with my wife savita patwari, age 67, were booked on flight @ 17.45 hours on hyd/chn flight no. 6e 598 on 5.3.24, where online boarding pass was issued to us. I was at airport security @ 4.15 pm, indigo bag drop @ 4.30-4.45 & also recd. Sms at 4.47 pm stating 25 min. To board. Bag drop counter staff said flight is already closed & wanted to confirm with her supervisor to allow us to complete formalities. Supervisor refused & directed us to another counter, where new boarding pass for flight 6e6617 were issued after collecting 5,000 each as penalty and did not issue receipt for same. This flight was to depart on 21:40 hrs. & boarding time was 20:55 hrs. Through gate 11. This flight was delayed & boarding was allowed at 22:17, flight gate @ 22:20, etd @ 23:11, eta 24:07 & baggage was out at 24:30 hrs.

Complaint is that I am frequent flier since over 50 years. I am a heart patient, stunt put on 30.4.22, pacemaker put on 17.11.23 & undergone 2 surgeries for gangerine in february 22.

Request an apology from the staff concerned for this type of treatment and also refund of extra amount collected for rebooking. My address is 1 chittaranjan road, teynampet, chennai 600018, ph [protected].
