At the Airport
Reading the Terminal: Finding Your Gate
Departure boards, gate numbers, walking times and boarding groups. How to navigate a terminal without stress.
Airside, an airport is a wayfinding problem. The information you need is all on the screens, but it arrives in stages and it changes.
The departure board
Boards list flights by departure time, with a status column and a gate column. Three things are worth understanding.
Gates are often assigned late. A blank gate column an hour before departure is normal at large hubs, where stands are allocated dynamically as aircraft arrive. The board is not broken.
"Go to gate" means walking time has been factored in and you should start moving. It does not mean boarding has begun.
"Final call" means the gate is closing. If you see it and you are not near the gate, walk quickly and do not stop for anything.
Walking times
Most large terminals print a walking time next to gate signage, and it is usually accurate for an unencumbered adult moving at a decent pace. Add time if you are with children, carrying a lot, or planning to stop.
Some airports separate gate piers by a train ride. Others require a second security check for certain destinations. Both add fifteen to twenty minutes that the departure board will not warn you about.
If your gate number is followed by a letter cluster you do not recognise, look at a terminal map before shopping. Working out at the last moment that your gate is in a satellite building is a genuinely stressful ten minutes.
Gate changes
Gate changes are common and they are announced on the screens before they are announced over the tannoy in most terminals. Check a board every twenty minutes or so while you wait, even after you have arrived at the gate.
Airline apps push notifications for changes. They are usually accurate and occasionally slower than the boards.
Boarding groups
Airlines board in sequence, and the sequence is printed on your boarding pass as a group number, zone or letter.
Groups exist to load the aircraft efficiently, not to reward you. Boarding early gets you locker space near your seat, which matters on a full flight with a large carry-on and matters very little otherwise.
The queue that forms twenty minutes before boarding does not move faster. The aircraft leaves at the same time whether you sat down or stood up.
Practical gate habits
- Locate the nearest toilets before you settle, not after boarding starts
- Find a seat near a power socket and charge, even if the battery looks fine
- Fill your water bottle at a fountain rather than buying another one
- Listen for your name if you are on standby or waiting for a seat change
- Keep your passport and boarding pass together, in a pocket, not in the bag
If you are late
Go to the gate first and sort everything else out later. Staff at the gate can act; staff anywhere else can only advise.
If the gate has closed, head back to the airline's transfer or ticket desk immediately. Options are usually better in the first thirty minutes than in the following three hours, and our guide on missed connections explains what to ask for.
