Flight Status Terms Explained (Delayed, Boarding, Gate Closed & More)
Flight Status Terms Explained
You check your flight status and see: "Estimated." What does that mean? Is it delayed? Is it on time? Should you panic?
Airlines and flight tracking apps use a set of standard terms to describe where your flight is in its journey. But they don't always explain what those terms mean for *you* as a traveler. Let's fix that.
Quick Answer
Here's every flight status you'll encounter, in chronological order:
| Status | What It Means | What You Should Do |
|---|---|---|
| Scheduled | Flight is planned but not yet active | Nothing yet — check back closer to departure |
| On Time | Flight is expected to depart as scheduled | Proceed to airport normally |
| Estimated | Departure time has been revised (often a minor change) | Check new estimated time, adjust plans |
| Delayed | Flight will depart later than scheduled | Check the delay duration and plan accordingly |
| Boarding | Passengers are currently boarding the aircraft | Get to the gate immediately if not already there |
| Gate Closed | Aircraft door is sealed, no more boarding | You missed boarding if you're not on the plane |
| Departed | Aircraft has pushed back from the gate | Your flight is underway (or taxiing) |
| In Air / En Route | Aircraft is airborne | Sit back, relax |
| Landed | Aircraft has touched down at destination | Head to baggage claim / arrivals |
| Arrived | Aircraft is at the gate, doors open | Passengers are deplaning |
| Cancelled | Flight will not operate | Contact airline for rebooking or refund |
| Diverted | Aircraft landed at a different airport | Wait for airline instructions |
Detailed Explanations
Scheduled
The flight exists in the system but hasn't entered active operations yet. Typically shown 24+ hours before departure. Nothing to worry about — this is the starting state for every flight.
On Time
The airline expects the flight to depart within 15 minutes of the scheduled time. This is the best status to see. Head to the airport with your normal plan.
Estimated
This is the one that confuses people most. "Estimated" means the departure or arrival time has been recalculated. It could be 5 minutes earlier OR later than scheduled. It doesn't necessarily mean a delay — it's just a more precise prediction based on current conditions.
Delayed
The flight will NOT depart on time. The airline has officially acknowledged a delay and typically provides a new estimated departure time. Reasons can include weather, air traffic control, mechanical issues, or crew problems.
When you see "Delayed," check the new departure time. A 15-minute delay is no big deal. A 3-hour delay might mean you need to adjust your entire plan.
Boarding
The gate is open and passengers are walking onto the aircraft. This is your signal that the gate is active and you need to be there NOW. Boarding typically lasts 20–35 minutes depending on aircraft size.
If you see "Boarding" on the status board and you're not at the gate — start moving. Fast.
Gate Closed
The aircraft door has been sealed. No one else is getting on that plane, no matter what. If you're not already on board, you've missed your flight.
This status appears 10–20 minutes before departure time. It's the hard cutoff, and airlines are strict about it.
Departed
The aircraft has pushed back from the gate. It may be taxiing to the runway, in line for takeoff, or already rolling. From your perspective as a traveler, the flight has left.
In Air / En Route
The aircraft is airborne, cruising toward its destination. If you're tracking someone else's flight, this means they're in the air and all is well.
Landed
The aircraft wheels have touched the runway at the destination airport. But the journey isn't over — the plane still needs to taxi to the gate, which can take 5–20 minutes at busy airports.
Arrived
The aircraft is at the gate with doors open. Passengers are deplaning. If you're picking someone up, they'll be at arrivals in 10–30 minutes (domestic) or 30–60 minutes (international, due to immigration and baggage).
Cancelled
The flight will not operate today. This is the status no one wants to see. Contact the airline immediately for rebooking or refund options.
Diverted
The aircraft was heading to one airport but had to land at a different one — usually due to severe weather, a medical emergency, or a technical issue. The airline will communicate next steps: either busing you to the original destination or rebooking you on another flight.
Real-World Example
You're tracking a friend's IndiGo flight 6E 2147 from Delhi to Mumbai:
- 6:00 AM: Status shows "Scheduled" — flight departs at 9:15 AM
- 7:30 AM: Status changes to "On Time" — everything on track
- 8:00 AM: Status changes to "Estimated 9:25 AM" — 10-minute delay, likely taxiway congestion
- 8:45 AM: Status changes to "Boarding"
- 9:10 AM: Status changes to "Gate Closed"
- 9:25 AM: Status changes to "Departed"
- 9:40 AM: Status changes to "In Air"
- 11:15 AM: Status changes to "Landed"
- 11:30 AM: Status changes to "Arrived"
You leave for Mumbai airport at 11:15 AM (when "Landed" shows) and arrive at arrivals just as your friend walks out.
Pro Tips
"Estimated" doesn't always mean delayed. It often means the airline has updated the time based on real-time data. Sometimes the estimated time is even earlier than scheduled.
"On Time" can change fast. Don't trust "On Time" status from 6 hours before departure. Check again 2 hours before. Weather and cascading delays can flip the status quickly.
"Departed" doesn't mean airborne. The plane has left the gate but could sit on the taxiway for 20+ minutes waiting for takeoff clearance. "In Air" confirms actual takeoff.
"Landed" doesn't mean at the gate. Large airports can have 15–20 minute taxi times from the runway to the terminal. "Arrived" confirms the plane is at the gate.

FAQs
What does "check-in open" mean?
It means the airline's check-in system is active for your flight (usually 24–48 hours before departure). You can now check in online or at the airport.
What's the difference between "delayed" and "cancelled"?
Delayed means the flight will still operate but later than planned. Cancelled means the flight won't operate at all.
What does "codeshare" status mean?
A codeshare flight is operated by one airline but sold by another. The status applies to the actual operating flight. If you booked with Airline A but it's operated by Airline B, track Airline B's flight number for the most accurate status.
What does "IROPS" mean?
Irregular Operations — airline-speak for when things go wrong (mass cancellations, severe weather, IT outages). During IROPS, many flights are delayed or cancelled simultaneously.
Can flight status change after I've boarded?
Yes. The plane can return to the gate after boarding (gate return) or even after pushback. Weather, mechanical issues, or security concerns can cause this.
