Over 50 flights were delayed by around 30 minutes after server of the check-in system at the IGI airport developed some technical problem this morning.
Due to some technical problem in the check-in system, which started around 4 am, airlines had to check-in manually, airport sources said.
As a result, around 50 flights got delayed by upto 30 minutes, causing inconvenience to the passengers.
Passengers had to stand for hours in long queues at all the airlines counters, they said.
Delhi International Airport Limited (DIAL), which operates and manages the airport, said that there was a problem in the check-in system due to which some flights were delayed by half an hour.
In a statement, DIAL said, "Due to a back-end problem in the system installed for check-in purpose, certain check-in counters went offline at Terminal-3. As a result, passengers on early morning flights were checked-in manually at some counters. No flights were cancelled. However, some flights were delayed by 15-25 minutes."
It said, "Systems were being brought back online by DIAL IT team as well as experts from the vendor of the proprietary system."
In the morning, each airline had five check-in counters operating normally while check-in had to be done manually at other counters.
"It is expected that all the systems will be functioning normally shortly," the statement said.
When the problem started at Terminal 3 of the IGI airport, there was no problem for the passengers then. But situation became bad when passengers started arriving for the morning flights.
IGI airport witnesses peak hour between 6 am and 9 am, when most of the outbound flights take off from New Delhi.
