Terrible check in
Pros: 1 hour check in at Kolkata to Delhi, at first wanted us to recheck bags at Delhi. Finally, bags checked through, but needed to get boarding passes in Delhi. In Delhi, 80 minutes at the desk before boarding passes. They suggested we didn't have return tickets, and kept asking for more information. And this was at business class desk! Finally took 4 of them at the desk to take care of it, and then we were so late couldn't get seats we wanted. Unbelievably bad! Beware!
