IndiGo flight cancellations to continue for some days
Details about Tuesday's cancellations
While eight flights were not operated from Kolkata, five flights were canceled from Hyderabad.
Additionally, four flights each from Bengaluru and Chennai were also canceled.
To make up, IndiGo reportedly forced its customers to buy last-minute tickets, or offered them alternate flights with one-stop connectivity and long layover times.
30 daily flights will be affected for a few days
Unfortunately for IndiGo passengers, the airline has said that such flight cancellations will continue for a while, with around 30 flights a day getting affected.
However, the airline has said that these adjustments would be "made in advance" to provide "adequate notice to passengers".
It has also said that "1-2% of originally planned flights" will be affected by these "adjustments".

A brief overview of IndiGo's flight operations
IndiGo has a fleet size of 209 planes, and operates around 1,300 flights on a daily basis, covering 52 domestic destinations and and 16 international ones. As of November, 2018, the budget carrier had 43% market share.
Why is IndiGo going through this problem?
The reason why IndiGo is facing this issue is two-fold.
According to an official, the disruption in flight operations stemmed from heavy rains and poor weather in the Delhi-NCR region last week, and the consequent issues surrounding flight duty and time limitation (FDTL) norms.
Both pilots and cabin crew are governed by DGCA-mandated FDTL norms, and cannot fly beyond FDTL limits.
