What an Airport Board Shows and How to Read It Without Mistakes
“Landed” and “Arrived” are not the same thing – there’s a 10-25 minute gap between them. “Delayed” shows up on the board later than the airline actually knows about it – the lag is 15-20 minutes. “Final Call” doesn’t mean you still have time; it means you’ll be pulled from the flight in 5 minutes.
Any one of these misreads can cost you your flight.
What each column on the departure board means
A standard row has 6-8 fields. Everyone watches the time and flight number, but status and gate update right up to the last minute – and those are the ones people miss.
| Column | What it shows | What to watch for |
|---|---|---|
| Time | Scheduled departure or arrival time | Always local time – don’t confuse it with the time on your ticket if you’re crossing time zones |
| Flight | Airline code + number (BA234, LH400) | Codeshare: one aircraft can carry 2-3 flight numbers at the same time |
| Destination / Origin | City or airport | May show the final destination, not your connecting point |
| Terminal | T1, T2, A, B, C… | Allow at least 45 minutes for a terminal transfer |
| Gate | A12, B7, C34… | Appears 1-3 hours before departure and can change |
| Status | Scheduled, Boarding, Departed… | The most important column |

Flight delays on the board
“Delayed” appears on the departure board later than the airline actually learns about the delay. Airport systems and booking systems refresh at different rates – the gap can reach 15-20 minutes.
If your flight is delayed, open the airline’s app – it updates faster than the public board. With Ryanair, EasyJet, and Wizz Air, push notifications about delays tend to arrive 10-15 minutes ahead of the board.
- If the board shows only “Delayed” with no new time, the delay is open-ended. Go to the airline’s desk or call their hotline.
- A delay of 3 hours or more within the EU entitles you to compensation under EC 261/2004 – €250 to €600 depending on flight distance.
- The updated time on the board may change several times – always look at the most recent figure.
- If the delay drags on or the flight is cancelled, you can look for an alternative yourself – flight search on Know.travel compares fares across different airlines.
Boarding will start 30-50 minutes before the new departure time, and the gate closes 10-15 minutes before that.
If you’re sitting in a café at the far end of the terminal, you can miss the flight even when the clock technically shows an hour to go.
Gate vs. terminal – what’s the difference
A gate and a terminal are different things. On the board they often appear side by side, which is where the confusion starts.
A terminal is a building. Large airports have several: London Heathrow has 5 terminals; Bangkok has two separate airports – Suvarnabhumi and Don Mueang – which people often mistake for terminals of the same airport. Getting between Heathrow terminals takes 20-40 minutes including the shuttle, but it’s free.
A gate is a specific door inside a terminal. Numbering varies: some airports run A1-A50 in order, others jump around. At Dubai (DXB), walking from gate C1 to C68 takes 15 minutes on foot.
When the gate appears depends on the airport:
- Small regional airports – 3-4 hours before departure
- Major hubs (Frankfurt, Dubai, Doha) – often only 60-90 minutes out
- Asian airports (Singapore Changi, Hong Kong) – usually 2-3 hours ahead, and gates almost never change
T2/B14 means Terminal 2, gate B14. If the board in front of you doesn’t show a terminal at all, you’re already in the right one – local boards only display gates within their own terminal. If the terminal shown isn’t yours, find the inter-terminal transfer first, then look for the gate.
Codeshares and why your flight isn’t on the board
Codesharing is why you sometimes can’t find your flight on the board. Iberia sells you a ticket as IB3456, but the aircraft is operated by Vueling as VY1234 – and the board shows VY1234 only. IB3456 isn’t there at all.
The board displays the operating flight – the one whose aircraft is actually flying. The number on your ticket is the marketing flight number, used only for the booking.
How to find your flight:
- Open the airline’s app or website – they usually show the operating flight number alongside your booking reference
- Use a flight tracker – FlightAware or Flightradar24 – enter your flight number and the system will identify the operating carrier
- The check-in desk will always tell you the operating flight number – just ask
Why you need an online flight tracker
The airport board shows scheduled times. An online tracker shows where the aircraft is right now – which city it’s over, its speed and altitude, and when it will actually land.
The main options:
- Know.travel Flight Tracker – our own tracker, free with no limits. Search by flight number (BA234, LH400) or by route, live map with the aircraft’s position, altitude, speed, estimated arrival time, and landing status
- Flightradar24 – the largest database covering commercial and private aviation worldwide. Full features require a paid plan (from $1.50/month); the free version has limited filters and history
- FlightAware – stronger on historical data and delay statistics for specific routes. Useful for checking how often a particular flight runs late
- ADS-B Exchange – non-commercial, shows military and government aircraft that are hidden on Flightradar24
A flight tracker is useful when:
- You’re picking someone up – you can see the plane is still over the sea and don’t need to rush to the airport yet
- The board shows “Delayed” with no new time – the tracker shows where the inbound aircraft currently is, so you can estimate when it’ll arrive and turn around
- You have a connection – you can check whether the incoming aircraft is on track to make it in time
What the board doesn’t show you
The board is intentionally stripped down – a fair amount of information never makes it onto the screen:
- Reason for the delay – you only get “Delayed”. For the reason, ask airline staff or check the airline’s official account on X (Twitter)
- Load factor – how many seats are filled. That data only exists inside the airline’s reservation system
- Aircraft type – occasionally shown as “B738” or “A320”, but usually not. Check Flightradar24 by flight number
- Accurate updated arrival time after a delay – the board lags behind. FlightAware or the airline’s app will be more current
- Baggage belt number on the departures board – that only appears on the arrivals board, and only after the plane has landed
Departure and arrival times on the board are always in the local time of that airport. Your ticket also shows local times, but separately for each city. Red-eye flights across multiple time zones can catch you out: a flight that leaves at 11:30pm and arrives at 2:15am isn’t 2 hours and 45 minutes in the air – it’s 8.5 hours once you account for the time difference.
Common mistakes when reading the board
I see the same errors play out at airports all the time.
Watching the time and ignoring the status. Low-cost carriers sometimes push back early if boarding finishes ahead of schedule. If the status says “Boarding” and you’re in a café 100 meters from the gate – move.
Going to meet someone the moment “Landed” appears. From touchdown to clearing baggage claim takes 20-40 minutes on short-haul flights and 40-60 minutes on long-haul. At Dubai, Doha, and Kuala Lumpur, the walk from remote gates to passport control alone can take 30-40 minutes.
Not rechecking the gate before boarding. Gates change more often than you’d think. At Heathrow, a gate switch 30 minutes before departure is routine. Set notifications in the airline’s app, or check the board again 40-50 minutes before departure.
Getting tripped up by codeshare numbers. If you can’t find your flight, search by destination and time rather than flight number. Then confirm the operating carrier.
It depends on the airport. Smaller regional airports typically post the gate 3-4 hours out. Major hubs like Frankfurt, Dubai, and Amsterdam often don’t show it until 60-90 minutes before departure. Asian airports like Changi and Hong Kong usually display it 2-3 hours ahead, and gate changes there are rare. If nothing is showing yet, check again 2 hours before your flight.
“Landed” means the wheels have touched the runway. “Arrived” means the aircraft has pulled up to the jetbridge and passengers are getting off. There’s a 10-25 minute gap between the two: the plane taxis to the stand and waits for an available gate. If you’re picking someone up, go by “Arrived”, not “Landed”.
Most likely it’s a codeshare: you bought a ticket from one airline, but the aircraft is operated by another. The board always shows the operating flight – the one that actually owns the plane. Find the operating flight number in the airline’s app or on Flightradar24 by entering your flight number. Or search the board by destination and departure time instead.
Call the airline’s hotline immediately or go straight to their desk at the airport – don’t queue at the general information counter. At the same time, open the airline’s app: rebooking options are often already available there. In the EU, if the airline is responsible for the cancellation, you’re entitled to compensation of €250 (flights up to 1,500 km) to €600 (flights over 3,500 km) under EC 261/2004.
No – the belt number only appears on the arrivals board after the aircraft has landed and been registered at the gate, typically 10-15 minutes after “Landed” status. At large airports like Heathrow, Frankfurt, and Dubai there are dedicated screens inside the baggage claim area – find your flight there and wait for the belt number to populate.
