Excellent question. This is a common concern for families traveling together.

The short answer is: Aer Lingus does not automatically guarantee that families will be seated together for free. However, they have a clear policy and several options to help ensure your family sits together, especially with young children.

Here’s a detailed breakdown of their policy and your best strategies:

  • If you haven’t paid for seats, check in online the moment it opens (usually 24
