Very worst experience!!! I had connecting flight from Ahmedabad to London..I took flight from Ahmedabad to Delhi .Then, went there for taking the connecting flight.I waited in the line for security checking.It took 1.30 to 1.45 minutes.I went at the gate around 15 minutes late because of there was not arranged security properly,and three line connected to one line.Flight was gone even they have bording pass with him.He was waiting for the next flight after purchasing the new ticket.
