What are my rights if I miss a connecting flight due to airline delay?

Under Irish law, the Air Navigation and Transport Act 1936 does not provide automatic compensation or rights for missed connections due to airline delays — your rights depend mainly on EU Regulation 261/2004, which applies in Ireland.

If your first flight was delayed and caused you to miss your connecting flight, the airline is usually responsible — provided both flights were booked together on a single ticket and the delay was not due to extraordinary circumstances.

If your connecting flight was missed due to a delay on the first leg and both flights were booked together on a single ticket, you’re likely entitled to compensation and assistance under EU Regulation 261/2004 (still retained in UK law post-Brexit).
