Flying from Kerry to Dublin? The short answer is no—you don’t need a passport. But the details matter more than you’d expect, especially since Aer Lingus tightened its rules for Ireland-to-Britain routes in February 2026. Here’s what you actually need to know before you show up at the gate.

Three airlines, three different ID policies, and one longstanding agreement that should make this simple but doesn’t. Here’s the breakdown.

Do I need a passport to fly within Ireland?

Irish citizens flying purely within the Republic—say, from Kerry to Dublin—don’t legally need a passport. Photo ID suffices under the Immigration Service Delivery guidelines for Common Travel Area travel. The CTA, established in 1923, comprises the UK, Ireland, the Isle of Man, and the Channel Islands, and has never legally required citizens to carry passports.

Kerry to Dublin example

  • A valid driver’s licence or public services card works for Irish citizens
  • No identity checks exist between Republic and Northern Ireland
  • Children and infants need their own passport or Irish passport card on Aer Lingus flights

The catch: while the law doesn’t mandate a passport, airlines can set stricter requirements than the state does. Ryanair and Aer Lingus both require more than just goodwill at the gate.

General domestic rules

  • Irish or British citizenship + photo ID = boarding for purely domestic flights
  • Non-CTA citizens need valid travel documents regardless of route
  • Ferry services accept more varied ID than airlines

Can you fly with Ryanair without a passport?

Ryanair requires all passengers to carry a passport or national identity card, not a driver’s licence or birth certificate, per their published policy and confirmed across multiple sources.

Ryanair ID requirements for domestic

  • Accepted: valid passport, national identity card (for EU/EEA citizens)
  • Not accepted: driver’s licence, birth certificate
  • For purely domestic Irish routes, the policy remains consistent—passport or National ID only

Driver’s licence acceptance

  • Ryanair help pages explicitly state they do not accept driver’s licence
  • Some confusion exists among travelers on Reddit about whether domestic routes differ
  • Best practice: bring your passport or national ID card to avoid gate problems

Can you fly with Aer Lingus without a passport?

Aer Lingus confirmed a policy shift on February 23, 2026, with implementation beginning February 25, 2026—requiring passports or Irish passport cards for passengers traveling between Great Britain and Ireland.

Aer Lingus valid IDs list

  • Passport (valid, any nationality)
  • Irish Passport Card (Irish citizens only)
  • Driver’s licence with photo (domestic flights only)
  • Prior to February 25, 2026: accepted bus passes, work IDs, student IDs

Travel to/from Britain notes

  • Irish and British citizens not legally mandated to hold passports under CTA
  • Aer Lingus Regional routes (Belfast-UK, Dublin-Donegal) exempt from new passport requirement
  • Emerald Airlines operates Aer Lingus Regional services
  • British Airways still allows photo ID on London City/Heathrow to Dublin routes
The catch

Aer Lingus claims streamlining document checks will speed up boarding, but Irish citizens who boarded with bus passes before February 25, 2026 now face a mandatory passport or Irish Passport Card for Britain routes. The airline frames this as harmonization; travelers call it a new barrier.

What ID is acceptable for Ryanair?

Ryanair’s official line: passport or national identity card only. Driver’s licences don’t appear on their accepted documents list for any route connecting to Ireland or Britain.

Domestic flights specifics

  • Valid passport from any country accepted
  • National identity card (EU/EEA citizens)
  • Irish Passport Card (Irish citizens)
  • No student IDs, bus passes, or work badges

CTA travel differences

  • Purely domestic Irish flights: same rules apply (passport or National ID)
  • Ireland to Britain: passport mandatory (Ryanair policy pre-dates Aer Lingus change)
  • Northern Ireland routes: no identity checks at land border, but airline gate checks still apply
Why this matters

Ryanair set the stricter standard first. Aer Lingus followed. British Airways remains the outlier, still accepting photo ID on London-Dublin routes. If you’re a frequent traveler between Ireland and Britain, one airline’s policy may suit you better than another’s.

Do you need a passport to travel to UK from Ireland?

Legally, no. The CTA explicitly states that Irish and British citizens aren’t required to carry passports when traveling within the area. But carriers—not the state—decide what happens at the gate.

Ryanair and Aer Lingus rules

  • Ryanair: passport or National ID mandatory for all Ireland-Britain routes
  • Aer Lingus: passport or Irish Passport Card for GB-Ireland flights since February 25, 2026
  • British Airways: photo ID still accepted on London City/Heathrow to Dublin
  • Irish Government position: no legal requirement for passports on CTA journeys

Common Travel Area exemptions

  • 5 regions in CTA: UK, Ireland, Isle of Man, Channel Islands (note: British Overseas Territories like Gibraltar excluded)
  • Children need own passport or Irish Passport Card (Aer Lingus policy)
  • Ferry services accept varied ID even for Ireland-England routes

What’s confirmed and what’s still unclear

Confirmed facts

  • CTA has existed since 1923 and covers the UK, Ireland, Isle of Man, and Channel Islands
  • Irish and British citizens not legally mandated to hold passports within CTA
  • Aer Lingus required passports for GB-Ireland flights from February 25, 2026
  • Ryanair already mandated passports for Ireland-Britain flights before Aer Lingus change
  • British Airways maintains photo ID acceptance on London-Dublin routes
  • Aer Lingus Regional routes exempt from passport requirement

What’s unclear

  • Whether other low-cost carriers will follow Ryanair/Aer Lingus
  • Specific enforcement details for non-compliance at gates
  • Impact data on passenger complaints since February 25, 2026 implementation
  • Whether connecting flights through Dublin or London fall under same rules
Bottom line: Irish and British citizens don’t legally need passports for CTA travel—but for flights between Ireland and Britain, Ryanair and Aer Lingus demand passports anyway. British Airways remains the option for those who prefer photo ID. If you’re flying purely domestic within Ireland, your driver’s licence still works. Check your airline before you pack.

Irish citizens do not require a passport to travel within the Common Travel Area. However, carriers may require photo identification.

Frequently asked questions

Do I need a passport for flights from Kerry to Dublin?

No. For purely domestic flights within the Republic of Ireland, Irish citizens need only photo ID such as a driver’s licence. There’s no legal requirement for a passport, and no identity checks between regions.

Is a driving licence enough for Ryanair domestic?

No. Ryanair requires a passport or national identity card for all routes involving Ireland or Britain. Their help pages explicitly state they do not accept driver’s licences.

What happens without valid ID on Aer Lingus?

You won’t board. Aer Lingus gate staff check documents before you reach the jetway. If your passport or Irish Passport Card is expired, damaged, or missing, you’ll need to rebook or provide acceptable alternative documentation.

Does Common Travel Area apply to all airlines?

No. The CTA is a government arrangement between the UK and Irish states. Individual airlines set their own document requirements. Ryanair and Aer Lingus now require passports for cross-border flights; British Airways still accepts photo ID.

Are there changes effective 25 February?

Yes. Aer Lingus implemented mandatory passport or Irish Passport Card requirements for all passengers traveling between Great Britain and Ireland on February 25, 2026. Aer Lingus Regional routes remain exempt.

Can I use a student ID for domestic flights?

Ryanair: no. Aer Lingus (domestic-only flights): possibly, but the airline has tightened acceptance. International student IDs were accepted before February 25, 2026 on Aer Lingus; after that date, their status is unclear for domestic routes.

Do ferry rules match flights to UK?

No. Ferry services operating between Ireland and England continue to accept varied identification—including documents that airlines no longer accept. If you prefer to avoid passport hassles, the ferry remains a more flexible option for CTA travel.
