The short answer
Use the official Manage Trip route to review available seats and extras for your booking. Seat options and charges can depend on the flight and fare. Confirm arrangements again after an itinerary change.

Aer Lingus seat selection: decide what matters
Decide whether your priority is sitting with a child, an aisle position, extra space or keeping a group together. Tell the issuer the requirement rather than only a seat number. Aircraft layouts can differ between flights.
Compare the full journey
Review each segment and each traveler. A seat purchase on one flight does not tell you what is included on an onward flight. Before paying, check whether the price shown is per person and per segment and whether your fare already includes a selection.
When plans change
Keep the seat receipt separately from the flight confirmation. After a rebooking, compare the updated seat assignments with the original ones. If a paid extra no longer appears, ask the seller or airline what happened and what options apply.
Accessibility is a separate conversation
A preferred seat is not a substitute for arranging accessibility assistance. Use the official airline assistance process for a specific access need. Discuss the journey with the airline early enough for it to consider the arrangements.
Common questions
Can you guarantee adjacent seats?
No. Availability and airline assignment decisions control the outcome.
Is a seat-map screenshot a confirmed seat?
Look for the assignment in your confirmed booking and keep any purchase receipt.
Can I request assistance through this website?
This site does not submit airline accessibility requests. Follow the official contact route.
