You can register your child with Miles & More from the age of 2 years and above. Airlines generally allocate children their own seat from that age which entitles them to earn miles.

Yes, you can absolutely earn frequent flyer miles for your child, and it is a highly recommended strategy for families in 2026. Most major airlines, including Delta, United, and Singapore Airlines, allow you to open a frequent flyer account for a child as soon as they are old enough to have their own "paid seat" (typically 2 years old). Unlike adults, children's miles often have enhanced expiry protection; for example, Lufthansa's "Miles & More" prevents a child's miles from expiring until they turn 18. To maximize these rewards, look for airlines that offer "Family Pooling" or "Mileage Pooling," such as JetBlue, British Airways, or Air Canada. This allows you to link your child's account to yours so that the entire family's miles are combined into one pot, making it much easier to reach the threshold for a "free" award ticket or upgrade. Even if your child only flies once a year, those miles add up, and by starting their account early, you are building a valuable travel fund that can be used for their future college trips or family vacations.
