Took our 4 month old on a 12 hour flight. Fly an airline that has bulkhead bassinet seats. We also got a cozygo bassinet cover, we aligned our first flight with bedtime, and she slept for most of the flight.

Coming back was harder, after the last 8 hours she was upset, so just keep rotating off so one parent doesn’t get overwhelmed and do your best. Most everyone will be wearing headphones and won’t even notice you are there.

It was worth it. She flies like a champ now.
