Lise - we are flying when our baby will be exactly 10 weeks old. We first took DS on a plane when he was 4 months old. It is so much easier when they are little they dont know anything. One suggestion is to either feed baby (Can be difficult because they are strapped to you) or give them a bottle of water with the smallest teat as it makes them suck hard and helps pop their ears. DS was 2.5 the last time we flew and we still gave him a bottle. Hope this helps.
