We are planning to go on a trans-atlantic flight (> 10 hrs) with an infant. To help defray costs, we're considering just getting a "lap" ticket for our (would-be) 1 year old. 

Are there airlines which are particularly good at accommodating infants? I would think these are the criteria:

 1. Shortest layovers.
 2. Most legroom in Economy.
 3. Accommodating, in terms of infant engagement (toys, puzzles, etc.) during the flight, seat assignments with bassinets capabilities, etc.

Our Route Sector will be to fly east from the US east coast (NY or DC), via Europe, to China/India. The final destination will be contingent based on scheduling, pricing and the answer to this question ;)
