Had a great experience with Spicejet from varansi to Mumbai in the air but a pretty poor one on the ground with this airline.
At check-in the Spicejet employee asked to see the credit card I booked the tickets with. I explained that between booking my tickets and travelling, my card had expired and I had been given a new one by my bank.
Hardly a rare occurrence, I would assume. I had to explain this to him three times but he still asked the same question. He eventually called his supervisor who also asked me the same question, forcing me to explain again. She then called another supervisor who checked my passport and let us check in. This caused quite a delay and unnecessary annoyance. However, when we boarded and departed ( on time) the service was excellent - friendly and welcoming cabin staff, clean and comfortable cabin with decent leg room ( I'm 6'1 and it was more than ok for a few hours) and good value/tasty food. I'd definitely fly with Spicejet again.
