(LONDON) Travelers from the UK, Spain, Canada, and the United States face another rough week as widespread flight cancellations and long delays grip London Heathrow and Barcelona‑El Prat, disrupting summer plans and critical trips across Europe and the Atlantic. Airport advisories and airline updates point to a mix of adverse weather, operational bottlenecks, and major labor strikes in Spain that together are hammering schedules and leaving terminals overcrowded.
On August 19, London Heathrow logged 48 flight delays and 17 cancellations in one day, hitting services operated by British Airways, Air Canada, American Airlines, United Airlines, Delta, Emirates, Qatar Airways, and Air France. Heavily affected routes include Vancouver, Chicago, Toronto Pearson, Amsterdam, and Barcelona. Passengers reported packed halls, long lines, and limited same‑day rebooking choices as aircraft and crews fell out of position.
In Spain, the situation at Barcelona‑El Prat is shaped by rolling labor action. Strikes by subcontracted ground handling workers—including staff employed by Menzies and Ryanair’s subsidiary Azul Handling—began on August 15 and are set to continue every Wednesday, Friday, Saturday, and Sunday through December 31, 2025. The walkouts, led by unions UGT and CGT, hit baggage, check‑in, and ramp services.
During August alone, Barcelona recorded 159 flight cancellations and 77 flights delayed more than 3 hours, with ripple effects felt at other Spanish hubs such as Alicante, Palma de Mallorca, Malaga, and Tenerife South on selected dates tied to the Menzies Aviation strikes.
High season demand makes recovery harder. Airlines say spare seats are scarce on transatlantic and intra‑EU routes, so missed connections can strand travelers for days. Recent examples include the cancellation of BA485 (Barcelona–Heathrow) on August 17, and from London: BA297 to Chicago O’Hare, UA941 to Newark, and AA81 to Dallas–Fort Worth, all pulled on August 5 as storms and staffing shortfalls converged.
Latest disruptions and who is most affected
- Routes linking London Heathrow and Barcelona‑El Prat to North America are taking the hardest hit, especially flights to and from the United States 🇺🇸 and Canada 🇨🇦.
- Heathrow faces weather, high passenger volumes, and staffing gaps, while Spain’s airports face recurring ground handling strikes that are outside airline control.
- Airlines report jammed phone lines and slow refunds as teams work through backlogs.
- Airport officials urge travelers to check flight status before leaving home and to arrive early for check‑in and security.
Families on holiday, workers on short business trips, and students moving for autumn terms all feel the strain. A missed long‑haul flight can upend visa start dates, school check‑ins, and job onboarding. According to analysis by VisaVerge.com, the timing—late summer and early fall—amplifies the impact because many travelers have fixed entry windows or non‑refundable housing on arrival.
Passenger rights and practical steps
Under EU Regulation 261/2004, passengers on flights that depart the EU—or flights operated by EU carriers—may claim compensation up to €600 for long delays or cancellations, unless the cause is an “extraordinary circumstance.” Strikes by third‑party airport ground handlers, like those at Spanish airports, are generally treated as extraordinary, so airlines are not required to pay compensation for disruptions caused solely by these strikes. However, airlines still owe care and assistance.
This care and assistance includes:
- Meals and refreshments
- Reasonable hotel stays when overnighting
- Transport between the airport and hotel
- Rebooking or refunds
Key points to remember:
- Weather and airport staff strikes typically do not trigger cash compensation.
- Technical faults or airline crew issues often do trigger compensation.
- Even when compensation is not due, airlines must offer care and options to rebook or refund.

Practical actions you can take now
- Check status early and often through your airline’s app or website. Turn on push alerts.
- If your flight is canceled, act fast in the app to rebook before seats sell out. If the app fails, try social media help teams and airport desks.
- Keep receipts for meals, ground transport, and hotels tied to the disruption; submit them to the airline for reimbursement where care is owed.
- If traveling on a tight entry window—such as start dates for studies or work—carry proof and ask the airline for the earliest re‑routing, even via alternate airports.
- Monitor Spain’s strike calendar if your trip touches Barcelona‑El Prat or other affected airports on Wednesdays, Fridays, Saturdays, and Sundays through year‑end.
Important: Strikes by subcontracted ground handlers are frequently classified as “extraordinary circumstances,” which can limit cash compensation. Still, airlines must provide care and reasonable assistance.
What to expect through late 2025
Unions say strikes will continue until new pay and conditions are agreed. Airlines and airports warn that weather and staffing pressures at Heathrow, combined with Spain’s labor action, could keep schedules fragile into the autumn.
The practical effects:
- A longer tail of missed connections and rolling flight cancellations, especially where aircraft and crews must rotate through Spain before long‑haul departures.
- Limited availability on peak routes, even when airlines are actively rebooking passengers.
- Continued advice from Heathrow and Barcelona officials to confirm flights before heading to the airport and to allow extra time for security and baggage checks.
Airlines involved in ongoing rebooking efforts include British Airways, Ryanair, easyJet, Air Canada, American Airlines, and United Airlines.
Risk‑reduction strategies for travelers
- Choose earlier departures in the day — they recover better when weather clears.
- Avoid tight connections; leave generous buffers, especially when switching from short‑haul to long‑haul.
- Hold flexible tickets or fares that allow same‑day changes without high fees when possible.
- If your journey depends on a fixed arrival date (visa reporting, school orientation, medical appointment), book backup options you can cancel.
If you need to escalate
- Keep communication in writing where possible (emails, app chat logs, screenshots of notifications).
- Save boarding passes, timestamps, and all receipts. Many claims resolve when travelers provide clear records of times, receipts, and the stated cause of delay.
- If an airline denies care that seems owed, escalate through its complaint portal and, if needed, national enforcement bodies.
Plan ahead; stay flexible.
