Revised Cabin Baggage Policy
Dear FOM,
As one of our most frequent travellers I am writing to let you know of some changes to our cabin baggage policy and to inform you of the additional carry on allowance for Gold Circle members.
From Monday 13th August 2012 all carry-on baggage must be within the size dimensions of 55cm x 40cm x 24cm.*
All passengers may also choose to bring into the cabin one of the following which must be placed under the seat in front of you :
– A Ladies Handbag / Gents Satchel (dimensions should not exceed 25cm x 33cm x 20cm)
Or
– A Baby Changing / Food bag
Or
– A Medical / Assistive Device
In addition to the above Gold Circle Club members will also be permitted one additional personal item e.g. a slimline laptop bag. This item should be stowed under the seat in front of you (if you are seated at Row 1 / or in an Emergency Exit Seat it should be stowed overhead).
Full details of our revised cabin baggage policy can be found on our website aerlingus.com
We greatly appreciate your custom and we look forward to welcoming you onboard in the very near future.
Kind Regards,
John Kavanagh
