Most travellers assume that if they have a passport, they are ready to travel.
In reality, airlines check more than just whether your passport exists — they check whether it meets specific entry requirements for your destination.
If it doesn’t, you may not be allowed to board your flight.
Many countries require your passport to be valid for at least 6 months beyond your travel date.
This means it’s not enough for your passport to still be “in date” — it must have sufficient remaining validity at the time of travel.
Travellers are often caught out because their passport expires soon after their trip, even though it hasn’t expired yet.
Some destinations do not require six months validity, but they still require your passport to be valid for the entire duration of your stay.
This creates a common issue where a traveller can technically enter a country, but their passport expires before they return home.
Airlines may identify this at check-in and refuse boarding if there is any risk your passport does not fully cover your trip.
A damaged passport may be treated as invalid, even if your personal details are still readable.
This can include:
Airlines may refuse boarding if your passport does not appear to be in acceptable condition.
Some countries require a minimum number of blank passport pages for entry and exit stamps.
If your passport is full or close to full, this can cause issues at the airport or on arrival.
This requirement is often overlooked but is still enforced in many cases.
Many travellers expect these checks to happen at immigration.
In practice, airlines carry out the first layer of checks before departure.
If a passenger does not meet entry requirements, airlines can be responsible for fines and return travel costs. As a result, checks at check-in can be strict.
Before heading to the airport, it is important to check:
These rules can vary depending on your nationality and destination, and may not always be obvious.
