Fliegen

Also mein Englisch ist zwar jetzt nicht das beste, aber hier besteht nun mal eindeutig nicht die Möglichkeit, einen extra Sitz zu buchen oder hab ich da tatsächlich was überlesen???:

Infants (between 0-5 months)

If the infant is under 6 months the child must sit on the adults' knee and will be charged a flat rate of €20/£19 or equivalent per one way flight on all shorthaul routes or 10% of the adult fare on flights from/to the USA.
Aer Lingus do not have a restriction on a minimum age that the infant should be, however they do recommend that you clear with your doctor that it is okay to travel up to the age of 2 weeks.
One adult cannot be responsible for more than two infants. Where one adult is travelling with two infants at least one of the infants must be over 6 months old and accommodated in a car type safety seat.
Infants are not permitted to occupy exit rows or the rows immediately forward or aft of an emergency exit row.
If both infants are under 6 months they must be accompanied by an additional responsible person.

Klar! Du musst dein Kind als 2-jährigen einbuchen! So machen wir das immer!
