The short answer
Aer Lingus announced a 10 kg baggage policy for Regional flights operated by Emerald Airlines from March 3, 2026. The published dimensions are 55 × 40 × 24 cm. Whether the bag goes in the cabin without an extra fee depends on what your fare includes.

What changed
The airline’s February 2026 announcement extends the policy across the Regional network. It says Plus and Advantage include the cabin option; Saver travelers can pay to bring the bag on board or check it into the hold without a bag charge under that policy.
How to check your own booking
Read the operator and baggage line on the confirmation. Find the difference between an included cabin bag and an option to check a bag. If your regional flight connects with a transatlantic journey, ask the issuer to confirm the allowance for the complete ticket.
Measure before you leave
Use a tape measure and check the external size with handles and wheels. Weigh the packed bag, not the empty case. If it needs to go in the hold, move items you must keep with you into an appropriate personal bag and check restricted-item rules.
When two pages disagree
Use the dated policy update and the current allowance in your booking as the starting point for a question to the airline. Save the relevant booking information. Avoid relying on a search snippet that still describes an earlier allowance.
Common questions
Is a 10 kg allowance automatically a free cabin bag?
No. The baggage policy distinguishes carrying the bag on board from checking it into the hold.
Does the update identify Regional flights?
The announcement identifies Emerald-operated Regional flights in the EI3000–EI3999 range.
What about a flight operated by another partner?
Check that operating carrier and your ticket conditions rather than applying the Regional rule automatically.
