Clever Ways to Score a Free Seat Upgrade on Your Next Flight
4. Get “Disrupted”

Flight disruptions can sometimes work in your favor when it comes to securing a better seat. If a delay exceeds four hours, a missed connection is caused by the airline, or an equipment change affects your assigned seat, politely requesting an upgrade as compensation may be successful, particularly for overnight or international flights. Pro Tip: If your seat or in-flight service is faulty (broken entertainment system, non-reclining seat), mention it to the flight crew. They may move you up if space allows.
