More than 300 flights taking off and landing in Mumbai in September were frequently delayed (delayed 20% of the times they operated).
According to the civil aviation ministry's list of most delayed flights, 195 city-bound flights and 114 flights taking-off from Mumbai consistently failed to stick to their schedule.
In April, the civil aviation ministry asked the Mumbai airport operator to draw a list of flights repeatedly missing their schedule so that air passengers could avoid such flights. The move was also aimed at disciplining errant airlines.
However, five months on, the number of frequently delayed flights is still high. Between April and September, the number of such flights marginally fell only in May.
"We will meet the airlines operations staff, air traffic control officials and airport staff to assess the problem next week," said a senior civil aviation ministry official requesting anonymity. The ministry is likely to cancel the existing take-off and landings slots of airlines repeatedly featuring in the delays list.
With the secondary runway shut for three months from October 10, airlines feel that such delays are likely to continue. "Managing with just one runway during the winter months could be a challenge," said a senior operations official with a private airline requesting anonymity.
In September, Jet Airways operated the highest number of frequently delayed arrivals with 49 of its flight making to the list. Kingfisher Airlines topped the list of flights with late departures. Comparably, fewer flights operated by low cost carriers made it to the list.
Some flights were delayed nearly every time they operated last month. For instance, an Air India flight AI 127 from Udaipur to Mumbai was delayed on 28 out of the 30 times it arrived in the city. Similarly, a Jetlite flight from Hyderabad, S2 456, reached the city late on 25 occasions out of the 28 times it operated.
