As my handle suggests, I spend most of my time here answering questions or providing advice on traveling with children. I think a revised and dedicated section on kid travel would be well received with simple tips that are difficult to find on the current co.com like: you can order kid meals (which are really great!) 24 hours in advance, most car seats won't fit into bulkhead seats due to the armrests, and that the big PCs do have kid rooms with double paned glass separating them from the rest of the PC.
Also, we often find ourselves on a Friday thinking "I wonder where we could fly for $200." How about a cheap last minute ticket search option where I would input departure city, maximum price per ticket, and maximum flight time? Then i would click enter and see what co.com spits back as options.
