Delay compensation (EU261 / UK261)

Measured by great-circle distance: 1,467 km.

Neither EU261 nor UK261 covers this route: it neither starts nor ends in the EU, EEA, Switzerland or the UK. Other countries have their own rules (for example Canada's APPR or Brazil's ANAC rules).

Close to the 1,500 km band edge
This route is within 50 km of 1,500 km, where the amount changes. Airlines and courts measure from the exact airport coordinates — check the figure they use.

Also owed for a cancellation with less than 14 days' notice or denied boarding. Not owed for extraordinary circumstances. On a connection, the distance to the final destination counts. From 23 October 2027 the EU's Regulation 2026/2202 applies; it keeps these amounts (what changes in 2027). Information, not legal advice.
