In spite of having covid-19 vaccination certificate spice jet security staff and officials were not allowing passengers for boarding. They are absolutely rubbish. I have been compelled to use such languages. I doubt spicejet officials and security staffs are illiterate or moron ! They are neither ready to listen to passengers nor ready to provide service. Cooperating with passengers is far away ! I'm not telling spicejet to do anything against rules. But spice jet guys should use their brains first to know and understand the rules and then only they should work ! They only harrase passengers. They are not professional and very rude also. They are so arrogant . I won't recommend anyone spicejet airline.
