I'll be flying from Liverpool airport with my 18 month old DS next month and have just checked in online and printed boarding passes. There were only two passes - one for me that mentions a 'plus infant' and one for DH. I remember flying with DS from Liverpool last year and I had massive trouble at security as they insisted DS have a separate boarding pass - I can't remember how I got round the problem. Does anyone know if this means I have to queue up and check in at the airport (even though I'm already checked in) so that they can give a separate boarding pass for DS? Thank you!
