A Winter Fog Season Checklist
for Flight and Train Delays
Every December and January, dense fog settles over Delhi, Lucknow, Amritsar, and stretches of the Indo-Gangetic plain, and travel plans that looked simple a week earlier fall apart in an afternoon. A flight holds on the tarmac. A train sits outside a station for three hours with no announcement. This is what to have in place before that happens to your family.

Why Fog Delays Are Different From Other Travel Delays
A monsoon delay usually comes with some warning, heavy rain is visible, forecasts are loud about it. Winter fog is quieter and less predictable. Visibility can drop suddenly in the early morning hours, hold for a few hours, and lift by mid-morning, only to return by evening. Flights get held rather than cancelled outright, trains run late by hours rather than being called off, and the actual duration of the delay is often unclear until it is almost over. That uncertainty is the hard part for a family trying to plan around it.
Before Fog Season Travel Begins
Check whether your route runs through a fog-prone stretch before you book
Delhi, the wider NCR, Punjab, and much of Uttar Pradesh and Bihar see the heaviest winter fog. If your flight or train passes through these regions between December and January, build in extra time on either end.
Share the exact flight number or train and PNR with the family circle, not just the departure time
A flight number lets anyone waiting at home check live status themselves during a long delay, instead of repeatedly messaging the traveler for updates while they are stuck at a gate with patchy signal.
Pack a power bank for anyone traveling through a fog corridor in winter
A multi-hour hold on the tarmac or outside a station means hours of extra phone use for checking status, calling ahead, and staying in touch, often with no charging point in reach.
Set a Place Alert for the final destination
When a journey is delayed by hours, the family circle finds out the moment the traveler actually arrives rather than everyone watching a flight tracker and guessing.
During a Long Hold on the Tarmac or at a Station
Once a delay starts, the most useful thing a family can do is stop asking for minute-by-minute updates. Airports and stations are often slow to give passengers new information themselves, so a traveler stuck in a holding pattern rarely has much to report beyond "still waiting." Agree on a check-in rhythm instead, such as once every hour, and let the rest of the wait be silence rather than a stream of "any update?" messages that the traveler cannot usefully answer.
When a Flight Diverts or a Train Is Rescheduled
Fog sometimes forces a flight to divert to a nearby airport rather than circle and wait, and a badly delayed train can occasionally be rescheduled from a different platform or even a different day for the return leg. This is exactly when a family waiting at home benefits most from a Place Alert or a quick look at the map, since it shows where the traveler has actually ended up, which may be a different city than the one everyone was watching the clock for.
Elderly Parents Traveling Alone in Fog Season
If a parent or grandparent is traveling by themselves during winter months, fog delays add a layer of stress beyond the usual worry, hours stuck in an unfamiliar airport or station, often with a phone battery not built for that kind of extended use. Confirming their phone is charged and Raksha is set up before they leave means the family can see they are safe and simply waiting, rather than calling every half hour to ask.
