He added, “Mumbai airport is still the busiest because of how many flights it handles. Besides regular passenger flights, it also deals with cargo planes, private jets and VIP movement. The congestion happens because there are too many flights scheduled too close together, and sometimes airlines don’t stick to their schedules, especially during busy times.”

Air congestion effect

Captain Ranganathan said, “Airports can only handle a certain number of flights at a time. But as more people want to fly, there are more planes, causing delays. When one plane is using the runway, another can’t land or take off, so it has to wait or hover in the air. This waiting makes flights late, and when many flights are late, it’s called congestion.”

“When planes have to wait in the air, they use up more fuel. Passengers get stuck on planes, waiting to land. They can’t leave until the runway is free and there’s a gate for them to park. This delay makes passengers uncomfortable and causes problems for airlines too,” he added.

Measures taken

The Ministry of Civil Aviation (MoCA) had stepped in to deal with the “constant congestion” at Mumbai airport. In a statement on February 13, the ministry said the congestion was caused by too many flights being scheduled too close together, airlines not sticking to their schedules, and unplanned flights during busy times. The ministry told the airport to make sure airlines followed the rules to ease the congestion.

The ministry in the statement said, “Mumbai airport is crowded, and that makes the airspace above the city crowded too. Flights end up circling the city for 40-60 minutes, waiting to land. To make things better, about 40 flights need to be cancelled every day to make sure flights can arrive and depart on time.” Earlier, on January 2, the Airports Authority of India (AAI) told Mumbai airport to reduce the number of flights from 46 to 44 per hour when the runway is busy, and from 44 to 42 when it’s not as busy.

What airlines say

IndiGo, in a statement, said, “As per directives to ease congestion at Mumbai airport, there have been certain cancellations from February 15 and affected passengers are being informed and provided with options to either avail a full refund, travel to an alternate sector or reschedule their flight.”

Akasa Air has stopped flights between Mumbai and Bengaluru until March 30 to help with the congestion.” Vistara has also cancelled eight flights per day from February 19 to February 30, according to sources. Air India didn’t say anything about the congestion, and an Air India Express spokesperson said they didn’t have many flights in Mumbai anyway.

Will reducing flights help?

Another aviation expert said, “Mumbai airport can’t handle any more flights. Things won’t get much better until the new airport in Navi Mumbai opens. When the new airport starts working, it will take some pressure off Mumbai airport. Until then, airlines will have to cancel flights, and it is likely more planes will stay on the ground.” Captain Ranganathan said, “Just cancelling flights for a while won’t fix the problem. When flights are cancelled, ticket prices usually go up because there are fewer seats. We need to look at why there’s so much congestion and fix that. We have to find ways to manage the congestion until the new airport opens.”
