There are plenty of details travellers need to be aware of in the build-up to their flight, and passports are a crucial part of that.
One thing that people might not know is that your passport needs to be in good condition, with no ripped or torn pages, water damage or holes.
This is so border control can make sure it is readable and hasn’t been fraudulently tampered with.
However, there are a few other rules that people need to be aware of and keep in line with.
3 passport rules that will stop you from flying
Two or more blank pages needed in passport
Your passport has lots of blank pages for border control to stamp when arriving or leaving countries.
However, what you might not know is that some nations require there to be at least two blank pages, otherwise they won’t let you through.
Natasha Inglis, Implementation and Client Success Director at Good Business Travel, explains: “Many countries require at least two completely blank visa pages (in some cases more) to allow room for entry and exit stamps or full-page visas.
“These rules are in place to make sure immigration officials have the space to properly document your movements and avoid complications at the border.
“Airlines may also check this at the boarding gate, as they could face fines if a passenger is later refused entry at immigration.
“This means travellers can be denied boarding before they even leave the UK if their passport doesn’t meet page requirements.”
Many European countries have this restriction, alongside African nations like South Africa and Kenya and Asian countries such as India, Thailand and Indonesia.
In Namibia, it is required to have up to six blank pages in your passport.
The UK passport has 34 pages, so it shouldn’t fill up too quickly, although if you’re a frequent flyer it might pose more of a problem.
Dr Mohanjeet Brar, MD of Gamewatchers African Safaris, suggests getting a jumbo passport if you fall into that category.
He said: “The UK offers passports with more pages (48 instead of 34), ideal for frequent travellers or those planning multiple-entry visas.”
Between three and six months of validity needed on passport
Since 2021, the EU has considered British travellers as ‘third country nationals’, which means travellers’ passports must have a minimum of three months’ validity remaining on the date you leave the EU.
Ian McIlrath, Managing Director at Ski Solutions, shares that you’ll need six months at the very least when visiting countries such as China, Australia, Thailand, Turkey, and Egypt.
Since these requirements vary by destination, you should always confirm the specific rules for your chosen country at the time of booking.
10-year issue date
Sean Doolan, director of ancillaries at travel insurance broker Swinton Travel Insurance, shares that if you’re travelling to EU or Schengen countries, your passport must have been issued within the last 10 years.
This is alongside the three months of validity needed as well.
He added: “If you fail to satisfy either of these requirements, you won’t be allowed to board your flight, because airlines are fined by governments if they carry passengers whose documents are not in order.”
UK passports are only issued for 10 years, so you might be wondering why this could be an issue.
This is because a previous rule meant you could carry up to nine months from an old passport onto a new one, which was the case before September 2018.
Matt Bramich, Operations Director at Inghams Walking, shares: “However, some UK residents will still have a valid passport that was issued before 10 September 2018, which may look like it’s valid for longer than 10 years.
“That’s because prior to this change, UK citizens were able to carry up to nine months from an old passport into a new one.
“However, this rule no longer applies for travel to the EU, which can cause confusion.
“In simple terms, the EU border authorities assess the validity based on the date of issue, not the expiration date.
“So, even if one of these passports still has months remaining before its printed expiry, it will be refused.”
New ETIAS rules launching in 2026
Alongside passport rules you need to keep in mind, travel to EU countries from the UK will be changing soon.

The European Travel Information and Authorisation System (ETIAS) is expected to begin operating in late 2026.
Once live, UK passport holders visiting 30 European countries for up to 90 days will need approval before travelling.
This will cost €20, but will be free for under-18s and over-70s and will be valid for three years or until your passport expires.
