Can I travel to the UK with an expired British passport if I have an Australian passport?

Possibly. The UK has told airlines they may accept an expired British passport if you also present a valid, ETA‑eligible Australian passport. Acceptance is at the carrier’s discretion. Bring both passports, printed confirmations, and arrive early for checks. Confirm with your airline in writing before you leave.

What do the UK ETA rules mean for dual nationals travel from Australia?

If your British passport is expired, airlines may board you when your second passport is ETA‑eligible. Policies can differ by carrier and route. Check for written confirmation from the airline, carry both passports, and leave extra time at check‑in. Rules are shifting, so recheck guidance 24 hours before departure.

What should I ask my airline before flying AU–UK this week?

Ask if they will board you with an expired British passport plus a valid ETA‑eligible second passport. Request they note your booking with both document numbers. Confirm any change fees, reissue rules, and minimum check‑in times. Keep a copy of the confirmation email or chat transcript for airport staff.

How could these changes affect airline costs or fares near term?

Airlines may face higher customer‑service loads, manual document checks, and more rebookings. That can lift costs and strain schedules. If confusion lingers, fares may shift as carriers manage loads and flexibility. Watch advisories, schedule completion, and management commentary for signals on margins and cash flow.
