1. Rights under EU Regulation 261/2004

This regulation protects passengers on flights departing from EU airports or EU airlines arriving in the EU. For the London (LHR) to Boston (BOS) flight, since LHR is considered equivalent to an EU airport (from a regulatory perspective post-Brexit, with the British Civil Aviation Authority maintaining similar protections), knowing these rights is essential.

  • Assistance: In the case of prolonged delays (more than 2-3 hours), assistance such as meals and drinks, two free calls, and if necessary, hotel accommodation, is provided.
  • Refund or Re-routing: In case of cancellation or delay over 5 hours, you can choose between a full ticket refund or rerouting to your final destination under equivalent conditions.
  • Compensation: For cancellations or arrivals delayed by more than 3 hours, monetary compensation ranging from 250 to 600 euros may apply unless the cause is extraordinary.

2. What to Do If Your Flight Is Delayed or Canceled

  • Check Flight Status: Visit the route page LHR-BOS for real-time updates and suggestions.
  • Go to the Airline Desk or Airport Assistance: to request support or rerouting.
  • Keep Your Documents: tickets, boarding passes, and any receipts are crucial for any future claims.

Practical Tips for Stress-Free Travel from LHR to BOS

  • Arrive Early: Heathrow is one of the busiest airports in the world; allow extra time for security checks and boarding.
  • Monitor Flight Status: Do not wait until the last minute to go to the airport, especially during peak seasons or bad weather.
  • Register for Delay Notifications: through your airline or app to receive quick updates.
  • Knowing Your Rights helps you manage potential inconveniences more calmly.
