There was no proper indication for going to gate no 7 for boarding at Coimbatore airport. First we go to upper side after seeing arrow but door was closed and directed us to go down, then left then take a lift to arrive at gate no 7. There were so many passengers who have faced this problem for boarding due to mismanagement. At Delhi, we were surprised to see that our one purple bag was missing. After enquiry with the staff, it was traced and we have got. Reason for this mismanagement was advised us that there was no tag on this bag, hence it was kept at downside. Who are responsible for not putting the tag at check in baggage counter at Coimbatore? Due to non putting the tag on bag, our valuable bag can be misplace which can also leads to mental tension to our family.
