You have just seen "Delayed" on a screen, or heard it announced, and you have about ten minutes before you need to decide what to do next. Here is what to do when flight is delayed, in an order that actually matches how the information becomes available: check the aircraft your flight depends on, check the airport's own status page, then talk to the airline, and save the record as you go. Skipping the order does not just cost time, it means you are often looking at a screen before it has anything new to tell you.
Check the inbound aircraft, not just your own flight
Most delays do not start with your flight. They start with the aircraft that is supposed to operate it, which is usually still finishing a previous leg somewhere else. This is a named, ordinary cause of delay, not a guess: a "late arrival of the aircraft to be used for the flight from a previous flight" is listed as a standard delay category on Wikipedia's overview of flight cancellation and delay (retrieved 2026-09-23). Airlines call this a rotation, one aircraft flying several sectors back to back, and a delay on an earlier sector rolls forward into every sector after it.
Once that aircraft is powered up or in the air, it broadcasts its own position. Automatic Dependent Surveillance-Broadcast (ADS-B) works because "each 'ADS-B Out' aircraft periodically broadcasts information about itself, such as identification, current position, altitude and velocity through an onboard transmitter," picked up "by ground-based ... or satellite-based receivers" (Wikipedia, Automatic Dependent Surveillance-Broadcast, retrieved 2026-09-23). In plain terms: if you know or can guess which aircraft is due to operate your flight, and it has not left its previous airport yet, you already have a real signal that your own departure is going to slip, often before the airline has said a word. This only works once the aircraft is airborne or powered up; a still-parked aircraft is not broadcasting anything to see, and ground-receiver coverage is dense near populated areas and thins out fast over open ocean, so this step is more useful on a domestic or regional rotation than a long-haul one.
Check the airport's own status page next
The airport's flight-information page is the next stop. Airport display systems typically pull from what the airline has already filed, rather than giving an independent read on the aircraft, which is the general shape a route-and-terminal lookup like this one implies. Delhi Airport's own flight-information section, for one, is built as a search by route and terminal, alongside separate departure and arrival filters (retrieved 2026-09-23): useful for confirming what has already been filed, and less useful for hearing about a change before the airline has filed it.
That is the practical takeaway. If the airport page or board has not changed yet, it does not mean nothing is happening; it can mean the airline has not filed the update on that channel yet. Checking here is your second read, after the aircraft, and before you spend time on hold with the airline over something that may already be visible.
Contact the airline directly, and have this ready
If the first two checks point to a real delay, or you just want to hear it from the source, go to the airline next: its app, its help desk, its social channels, or the number on your ticket. Before you do, have these ready so the call or chat takes one pass instead of three:
- Your PNR or booking reference and the exact flight number and date.
- The names on the booking, especially if anyone is travelling separately or connecting onward.
- Any onward connection details: the next flight number, the connecting airport, and the scheduled connection time.
- A way to be reached that you will actually check in the next hour, since some updates come by SMS or app notification rather than a phone call back to you.
Ask directly what the new expected time is, whether your booking is confirmed on any later flight the airline is already re-accommodating people onto, and what the airline needs from you if your plans change. An airline's own channel is the first place a decision is genuinely available, because the decision starts inside the airline before it reaches any board or app.
If you are travelling with others on separate bookings, or waiting for someone landing rather than departing, say so up front. An airline agent working from a booking reference can usually only speak to what is on that reference, so a connecting flight, a return leg on a different ticket, or a person you are picking up will each need their own check. This is also the point to decide whether you are staying put or moving toward a different gate, security line or terminal, since a rotation delay can mean a long, predictable wait rather than a short one, and it is easier to plan around a long wait once you know it is one.
Save the record as you go
Whatever you decide to do about the delay itself, keep a simple record while it is happening, not after:
- A photo of the departure board or the app screen showing the delayed status, with a timestamp.
- Any written message from the airline: an SMS, an email, an in-app notification, a chat transcript.
- The times you were given at each stage, written down as you hear them, since a verbal update at a gate desk is easy to forget by the time you need it later.
- Your boarding pass and baggage tag, kept together rather than in different pockets.
None of this takes more than a minute at each step, and it is the difference between having a clear timeline if you need to raise anything with the airline afterward, and trying to reconstruct one from memory a week later.
The 10-minute version
If you want the sequence without the reasoning behind each step, here it is in order:
- Check whether the aircraft due to operate your flight has left its previous airport yet.
- Check the airport's own flight-information page or the terminal board for the filed status.
- Contact the airline directly, with your PNR, flight number and connection details ready.
- Photograph the board, save any written message from the airline, and note the times as you hear them.
- Repeat step 1 and 2 every 20 to 30 minutes rather than refreshing constantly; a rotation delay does not usually resolve minute to minute.
The order matters more than any single step. Checking the aircraft and the airport page first means you spend your time on hold with the airline only once you already have a reasonably clear picture, and the record you kept along the way is there if you need it, whatever happens next.
How TrackMyWings helps
TrackMyWings™ is a live flight-tracking platform in development, India-first in go-to-market with worldwide coverage. A private, visual beta shipped 24 August 2026, Android only, on the Play internal testing track; there is no fixed public launch date, and it is gated on trade-mark clearance and the app reaching our own quality bar. What is published today, no install required, is the reference side of the site: the Delhi to Mumbai route page, IndiGo's own directory page and Delhi airport's page, for looking up a route or a carrier without opening an app first, alongside the rest of our flight-tracking explainers on how status information actually moves through an airline, an airport and a tracker. What is planned, written in planned tense because it has not shipped, is a live map and gate-and-status alert view built around the same ordering this playbook describes: the airline's own decision first, then confirmation as the aircraft moves.

Frequently asked questions
What should I check first when a flight is delayed?
Whether the aircraft due to operate your flight has left its previous airport yet, if you can identify it. Most delays start upstream, on an earlier leg the same aircraft was flying, so this is often the earliest real signal you can get.
Does checking the airport board tell me anything the airline app doesn't?
Not usually earlier. Airport flight-information pages, including the terminal boards, typically pull from what the airline has already filed, so in practice they tend to catch up shortly after the airline's own channel rather than ahead of it.
What should I have ready before I contact the airline about a delay?
Your PNR, exact flight number and date, the names on the booking, and any onward connection details: next flight number, connecting airport and scheduled connection time. Having these ready turns a multi-step call into one.
Is it worth taking a photo of the departure board?
Yes. A timestamped photo of the board, plus any written message from the airline, gives you a clear record of what you were told and when, which is far easier to have than to reconstruct later.
How often should I actually recheck once I know a flight is delayed?
Every 20 to 30 minutes is usually enough. A rotation delay traced to a late inbound aircraft resolves on that aircraft's own schedule, not on how often you refresh a screen, so checking constantly mostly adds stress without adding information.
