The check-in system at terminal 1B of the domestic airport in Mumbai collapsed on Sunday due to crashing of the server resulting in flight delays for some time causing inconvenience to passengers.
However, the system has now been restored and operations at the terminal are normal, a Mumbai International Airport Limited official said.
"The system remained down for 50 minutes due to which check-in could not take place through the computers and it was being done manually," he said.
The number of flights which got delayed due to the crashing of the system is yet to be ascertained, the official said. Private carriers Jet Airways, SpiceJet and IndiGo operate flights from terminal 1B while national carrier Air India and budget carrier GoAir operate from terminal 1A of the city's domestic airport.
