The December weather in Northern India often brings fog and haze, which severely affect flight operations. Low visibility during this time of year is a frequent cause of travel disruptions, with fog hindering air traffic control and making it difficult for pilots to safely navigate departures and arrivals. As a result, airlines often face scheduling issues and delays during the winter months, which can affect thousands of travelers. These weather conditions, while common in the region, continue to challenge the aviation industry every year.

Travelers have been urged to remain flexible with their plans and monitor the latest updates from IndiGo via its official communication channels. The airline has pledged to keep passengers informed and ensure they receive full support during this period of disruption.

In light of the ongoing disruptions, passengers are advised to check their flight statuses frequently and consider alternative travel arrangements in case of delays or cancellations. The airline is working diligently to restore normal services as soon as the weather improves, but in the meantime, passengers are advised to stay prepared and expect longer than usual waiting times at airports.

This latest round of cancellations serves as a reminder of how seasonal weather conditions continue to impact air travel in India, particularly in the northern regions, and highlights the need for travelers to plan accordingly during the winter months.
