Will there be change?

Relative was arriving from San Fransisco by Jet Airways. Scheduled arrival time was 8.45 am. As Typhoon was expected to hit Hongkong I phoned Mumbai airport for ETA. Jet Airways informed me that flight was arriving before time and ETA was 7.05 am!!. I rushed to the Airport. Arrival monitor on Mumbai Airport was displaying ETA for the flight as 8.45 am / on time. Flight landed at 7.05 am ,passengers started coming out at 7.45 am but Airport arrival Monitor did not indicate that flight has landed. Why we cant manage such simple things on International Airport is beyond my understanding. Railways under our Lalu Prasad is doing better job of providing real time info.---PK
