New Delhi: The departure lounge of terminal 3 of Delhi's Indira Gandhi International Airport on Saturday resembled scenes usually found at the more crowded railway stations in India, with passengers squatting on floors, thanks to the software glitch on Air India's servers that left thousands stranded. This, however, wasn't the first time the airline's software played truant — question is, will the airline ever learn?
An average delay per flight of 3 hours and 17 minutes greeted passengers travelling aboard Air India's 137 flights on Sunday — a day after 149 flights of India's national carrier were hit by a software shutdown of its passenger service system (PSS) that looks after check-in, baggage and reservation. Saturday’s 5 hour and 15 minutes shutdown, from 3:30 am till 8:45 am, caused a chain reaction on Sunday, on the airline's second and third sectors, with a distinct possibility of it being carried forth to today. An aircraft flies several sectors, or flights, in a day — so, for example, for an aircraft flying the Delhi-Mumbai-Bengaluru-Chennai route, Delhi-Mumbai will be the first sector, Mumbai-Bengaluru will be considered the second sector while Bengaluru-Chennai will be the third sector. Air India flies 674 flights daily.
This is not the first time Air India’s PSS has gone rogue — last year, in June, a similar outage lasting three hours affected 25 of the airline's flights globally. Incidentally, in both cases the software was being managed by SITA. While last year, the airline claimed the blunder was committed due to network connectivity issues at SITA's Atlanta data centre, this year's snafu has been attributed to system maintenance, which incidentally, affected only Air India, according to SITA, which also manages the software for other airlines such as Virgin Atlantic and Air Vistara, none of which were affected.
