I’ve been doing solo flights between Austria and Malaysia since my eldest was 9 months old. And have been doing it every year, sometimes twice a year. It’s a 1 hour transit flight to Germany and then a 12 hour flight to Malaysia. Now, my eldest is 8 years and my toddler is 20 months old. After going through numerous flights with toys and activities, some was unnecessary and some not, and considering the extra carry-on, I’ve come up with the best airplane toys for toddlers.
