Traveling With an Infant or Small Child
When traveling, infants and small children under 2 years of age must be accompanied by an adult.
Within the first 7 days after birth, a baby is not considered strong enough for air travel and will not be accepted as a passenger on an EVA flight.
EVA requires that a Medical Information sheet (MEDIF) certifying readiness for air travel be provided for premature babies.
For safety reasons, whenever two infants or small children are traveling with one adult, one must be able to sit in a seat using an approved car-type infant seat.
According to CAA regulations, an aircraft shall be equipped with a seat for each person who is over two years of age.
Beginning Nov. 1, 2004, infants who reach their second birthday while traveling on an EVA Air flight must, in accordance with safety regulations, begin to occupy their own seat. The applicable child's fare must be paid for all sectors flown after the child reaches two years of age.
If you would like to order a baby meal and/or diapers, please contact our reservations office at the time you make your booking. We will do everything possible to assist you.
Baby bassinets are available aboard all EVA Air aircraft, but for safety reasons, height and weight limitations apply. Please advise us of your baby’s date of birth, height and weight when you make your reservation.
*** The Chinese Version also says: (目前本公司皇璽桂冠艙未提供嬰兒搖籃且不可以使用兒童安全帶或兒童安全座椅).
Translated: Baby bassinets are not available in Royal Laurel Class and baby safety seats or baby seatbelts cannot be used in Royal Laurel Class at this time.
