British Airways is warning travelers of fresh flight cancellations and delays in August 2025 on routes linking Japan with the UK, Italy, France, and Germany. As of August 10, the airline reports 6 flight cancellations and 21 delays (2%), mainly tied to aircraft shortages and bad weather in London.
The main cause remains a lack of available planes, driven by delays in engines and parts for the Boeing 787 Dreamliner fleet. Summer storms around Heathrow and air traffic control issues in Europe are adding pressure.
Current situation
- On August 10, British Airways confirmed 6 cancellations and 21 delays across Japan–Europe routes.
- The airline cites slow deliveries of Rolls‑Royce Trent 1000 engines for its 787 Dreamliner aircraft, plus wider parts shortages.
- Analysts expect supply chain problems to continue into 2026.
- Weather and air traffic control disruptions are causing further same-day changes at Heathrow and other hubs.
A British Airways spokesperson said in November 2024:
“We’re disappointed that we’ve had to make further changes to our schedule as we continue to experience delays to the delivery of engines and parts from Rolls‑Royce – particularly concerning the Rolls‑Royce Trent 1000 engines fitted to our 787 aircraft. We’ve taken this action because we do not believe the issue will be solved quickly, and we want to offer our customers the certainty they deserve for their travel plans.”
Wider network changes affecting connections
While the latest numbers are small, they sit on top of earlier cuts:
- London Heathrow–Kuala Lumpur: suspended until April 2025.
- London Heathrow–Dallas/Fort Worth: ended March 30, 2025.
- London Gatwick–New York JFK: suspended December 2024 to March 2025.
- Heathrow–Miami: reduced to once daily for summer 2025.
About 200,000 passengers have felt the impact of these longer route suspensions and reductions this year. If you connect through London or Europe for a Japan trip, your itinerary may still be at risk, especially during summer storms.
Your rights if your flight is disrupted
Under UK and EU rules:
- Full refund: You can ask for your money back if your flight is canceled.
- Rebooking: You can move to the next available British Airways service or a partner airline at no extra cost.
- Compensation: Up to €600 / £520 if cancellation happens within 14 days and it’s within the airline’s control (e.g., mechanical issues). Weather and air traffic control usually don’t qualify.
- Accommodation: If rebooking is the next day, the airline should provide a hotel and meals.

Immigration and visa concerns to consider
Flight cancellations can spill into immigration problems. Keep these points in mind:
- Visa validity: If your visa or visa waiver is close to expiring, a long delay could push you past your allowed stay. Keep proof of the delay (airline messages, boarding passes) and contact the local immigration office if you risk an overstay.
- 90/180‑day Schengen rule: If you’re on a short‑stay plan and a delay adds days, collect evidence from British Airways to show you didn’t intend to overstay.
- UK visitors: If a change forces you to land after your planned exit, keep your rebooking proof. UK border officers usually review evidence of genuine delay and rebooked travel.
- Appointments: Students and workers might miss biometrics or visa interviews. Email the embassy or visa center with your airline delay documents and ask for a new appointment.
- Transit visas: If you now connect through a different country, you might need a transit visa. Check this before you accept rebooking to avoid being denied boarding.
According to analysis by VisaVerge.com, travelers who save all airline notices, hotel receipts, and transport costs tend to have smoother conversations with immigration officers and better outcomes on expense claims later.
Practical steps to take now
- Check status often. Use the British Airways website or app for live updates: British Airways Flight Status: https://www.britishairways.com/main/flightstatus/en_gb
- Rebook or refund. Go to Manage My Booking for options and policies: https://www.britishairways.com/content/information/delayed-or-cancelled-flights
- Call for help. If you need a human fast, use the dedicated helpline: 844‑928‑0428.
- Try live chat. British Airways offers real‑time support on its website, helpful when phone lines are busy.
- Keep documents. Save emails, app alerts, photos of airport screens, and receipts for meals, lodging, and transit—these support compensation claims and may help with immigration questions.
- Think about connections. If rebooked through a new country, confirm transit visa rules before you accept the change.
- Book flexible tickets when possible. Pick fares you can change without heavy fees while supply chain problems continue.
Who is most affected
- Students traveling to autumn terms in the UK, France, Germany, or Italy may miss inductions. Ask schools for letters confirming late arrival due to flight cancellations.
- Skilled workers starting new roles should tell HR early and share proof of airline changes; employers may adjust start dates.
- Families and tourists on tight schedules might lose prepaid tours. Keep receipts; you may claim reasonable costs if the airline is at fault.
Why this keeps happening
The Boeing 787 Dreamliner fleet needs a steady flow of Rolls‑Royce Trent 1000 engines and parts. Shortages worsened in 2024–2025 because of limits on raw materials and manufacturing slots. International Airlines Group (British Airways’ parent) says weather and air traffic control issues in Europe are also causing knock‑on disruption this summer. Industry watchers expect only slow relief in 2026 as engines arrive and grounded aircraft return to service.
Workarounds and partner capacity
On some North Atlantic routes, partner airlines—especially American Airlines—are adding seats to cover gaps from British Airways schedule cuts to Dallas and Miami. If you’re offered a rebooking on a partner, check:
- Transit visa needs on the new routing.
- Baggage allowance and special item rules (sports gear, etc.).
- Special service requests (wheelchair, bassinet) are confirmed on the new ticket.
A short case study from Tokyo
A graduate student flying Tokyo–London–Milan for a university start date loses the London–Milan leg to a same‑day cancellation after storms over Heathrow. She:
- Rebooks to a later Heathrow–Milan flight.
- Messages her university with proof of delay for a late check‑in.
- Keeps meal and hotel receipts for a claim.
- Enters Italy one day late with airline evidence ready at border control.
She reaches class the next morning and later receives partial expenses back because the missed connection was linked to operational issues.
Key takeaways
- Expect scattered changes on Japan–Europe routes through 2025, with more stability only when engine supplies improve.
- Know your rights: refund, rebooking, and in some cases compensation up to €600 / £520.
- Protect your immigration status by keeping proof and contacting authorities if a delay risks an overstay.
- Use British Airways tools quickly—online, live chat, or the 844‑928‑0428 line—to secure the best rebooking options.
