School: Infant, Pack n Play

International Flights with an Infant

I'm considering an international trip over the next year so my baby and her father can see his side of the family - we would go to India and/or Hong Kong. Has anyone ever traveled internationally with a child under 1? What should I pack, check and carry on? I'm not sure if I need things like a car seat, pack-n-play, etc. Suggestions on smart packing (how to not overpack) and travel tips with a baby (how to fly 24 hours and keep her as happy/comfortable as possible) would be appreciated!
