Seat Downgrades, Empty‑Seat Moves & What You Can Claim (EU261 Tool)
If a booked cabin is changed to a lower class, a partial refund of the airfare portion is due within seven days under EU rules. Moves to other seats may be limited by weight & balance and class policies. Use the calculator, quick checks, and ready text below.
What changed at the gate?
Seat downgrades can occur after an aircraft swap, an operational overbooking, or to balance the cabin. The originally booked seat cannot be created on board, but the fare difference is not carried by the passenger when a downgrade occurs under EU air passenger rights. For airport rules, related policy shifts and capacity stories, see: capacity trims and airport performance data.
