Furthermore keep in mind that purchases made at airports, such as larger duty-free purchases, count toward your baggage limit. You may bring one more standard item if you are carrying your baby on your lap while traveling. you can bring 1 additional standard article for your child’s belongings. All carry-on baggage rules are strictly enforced. All bags that do not respect maximum sizes will need to be checked, and additional checked baggage charges may apply. No matter where you're going, you can only bring 1 standard item and 1 personal item. Wheels and handles are included in the maximum size.
