Airport English boils down to four sets of phrases: check-in and baggage, security, finding the gate, and delays. Two security rules are worth memorising: a power bank must go in your carry-on and is never allowed in checked baggage, with a capacity limit of 100Wh, and liquids must be in containers of 100ml or less inside a clear, sealed bag.
1. A walk through the whole sequence
Picture yourself pushing a trolley towards the airline counter:
I arrive at the airport three hours before my flight. I find the check-in counter for my airline. There is a long queue, so I wait patiently.
When it is my turn, the staff says, "Good morning! Can I see your passport and flight booking?" I hand them over and say, "I'd like to check in for my flight." She asks, "How many bags are you checking in?" I place my suitcase on the scale. I am worried, so I ask, "Is it overweight?" She smiles and says, "No, it's just 22kg. You are fine."
Then I make a request: "Could I have a window seat, please?" She checks and gives me my boarding pass. "Your flight departs from Gate B4. Boarding starts at 6:30 PM." Next, I head to security. I put my laptop and liquids in a tray. After passing security, I am ready to fly!
2. Check-in and baggage
- I'd like to check in for my flight.I want to complete check-in.
- Can I have a window seat / an aisle seat?Requesting a specific seat.
- Could I have a seat with extra legroom?Asking for a roomier seat, e.g. at an exit row.
- Is my luggage within the weight limit?Checking before the bag goes on the scale.
- What is the excess baggage charge?Ask before you agree to anything.
- Please mark this bag as "Fragile".Essential if you are carrying anything breakable.
- Can I take this as carry-on?For items you would rather keep with you.
3. Security
- Do I need to take off my shoes / belt?Rules vary by airport and country.
- Should I take my laptop out of the bag?Usually yes, but not everywhere.
- Are these liquids allowed in my carry-on?Useful if you are unsure about a container size.
- I have a power bank in my bag.Power banks must never go in checked baggage.
- Where should I put my tray?When the conveyor layout is unfamiliar.
4. Gates and delays
- Where is Gate [Number]?The single most useful airport question.
- Is the flight on time?Worth asking at the gate screen, not just reading it.
- Has the flight been delayed or cancelled?Phrase it as a direct question if you need confirmation.
- Which gate does this flight depart from?Gate changes are common at large airports.
- Am I in the right queue for boarding?Boarding groups catch people out.
5. Practical warnings
Power banks
Security is strict about power banks: they must be carried in the cabin and are never allowed in checked baggage. Capacity is usually limited to 100Wh (roughly 27,000mAh); anything larger may be confiscated. If asked, say: I have a power bank in my bag.
Liquids
Containers must not exceed 100ml and must be inside a transparent sealed bag. If you buy perfume at duty-free, make sure staff seal it in a security bag with the receipt visible — you may be asked to show it when transferring.
Strong-smelling food
Some airlines prohibit durian and other strong-smelling foods from both checked and cabin baggage, even vacuum-packed. Eat it in town before you leave.
KLIA train transfer
At Kuala Lumpur's KLIA1, gates may be in the satellite building, which requires a train or bus transfer. Allow generous time rather than cutting it fine.
6. Core vocabulary
| English | Notes |

| Gate | Where you board |
| Boarding time | Usually 30–60 minutes before departure |
| Final call | Your last warning to reach the gate |
7. Two expressions worth knowing
"Final call" — hearing this while browsing duty-free does not mean the flight is near; it means run. The gate closes shortly afterwards.
"Upgrade" — if you are feeling lucky, try "Is there any chance for an upgrade?" at the counter. Sales or a quiet premium cabin occasionally produce a surprise.
Reading them once will not stick. Using them once will. Run through this page on the way to the airport, and concentrate on the three to five lines you will genuinely say on this trip.
Frequently asked questions
How do I handle an overweight bag?
Ask What is the excess baggage charge? first. If you are travelling with someone who is under their allowance, ask Can we combine our baggage allowance?
Can I ask for an upgrade?
Yes — Is there any chance for an upgrade? Your chances improve when the flight is oversold or premium cabins are quiet.
Can power banks go in checked luggage?
No. They must travel in the cabin, are usually limited to 100Wh (about 27,000mAh) and must be clearly labelled.
Will duty-free liquids be checked when I transfer?
Possibly. Have staff seal them in a transparent security bag and keep the receipt visible — you may be asked for it at the transit security check.
