Common Causes of Delays and Cancellations on ORD-LHR
Delays and cancellations can result from multiple direct or indirect factors:
- Adverse weather conditions: especially near Chicago and the UK, conditions like fog, thunderstorms, or snow can cause delays.
- Airport congestion: both Chicago O’Hare and Heathrow are among the busiest airports globally, with times of significant congestion.
- Technical or operational issues with the airline: which can lead to delays for repairs or aircraft substitutions.
- Security and passenger control matters: border or security checks can impact boarding and arrival times.
EU Passenger Rights under EU261 Regulation
If you are traveling to London Heathrow, it is important to know your rights regarding delays and cancellations under Regulation (EC) No. 261/2004 – known as EU261. Although ORD is a non-EU airport, since London Heathrow is an EU airport at the time of flights (pre-Brexit) or subject to similar rules, some cases may fall under EU261 protections, especially for flights to the EU operated by EU carriers or under relevant agreements.
What EU261 covers:
- Extended delays: if a flight arrives more than 3 hours late.
- Cancellations: with at least 14 days’ notice required or offers of reimbursement or rebooking.
- Denied boarding: due to overbooking or other reasons.
- Monetary compensation: ranging from €250 to €600 based on flight distance, if causes are attributable to the airline and not external factors like extraordinary weather.
How to claim compensation:
- Always keep your flight documentation (tickets, boarding passes).
- Collect official information about the delay or cancellation.
- File a complaint with the airline (American Airlines generally has clear procedures).
- If needed, use assistance services or portals like FlightGuard to check risk and confirm your rights.
