We flew from Vegas to Dayton, when my daughter was one week old...to get her home. The plane sound kept her asleep the entire flight, people remarked they didn't even know a baby was on board. Second trip Ohio to FL when she was 4 mos old, no problems (except finding a plance to change her) she had a bottle and her pacifier then. At 1 year, it was a little trickier, she wanted to walk around and explore not stay in her seat. No ear problems until she was 4.
