I'm trying to book award seats for next year on Aer Lingus Regional, operated by Emerald Airlines. SOU (Southampton) to DUB. Travelling will be my adult daughter and her six year old child. I have tried multiple dates and it looks like there is only ever one award seat available for this route. So what to do? I can't book an adult award seat and then a revenue child seat as a separate booking. Any bright ideas, please?
