Flying with very young children has its own peculiar complexities. Usually, foreign airlines provide better on-board and airport amenities including toys, baby-formula and diapers to families traveling with kids when compared to US airlines.
Some of the most kid-friendly international airlines are Emirates for flights to the Middle East and further, Lufthansa and British Airways for Europe and Singapore Airlines for Asia. Emirates has a special frequent flyer program for kids and may even offer cakes to the kids flying on their birthdays.
