I was the person who provided the original info to Margery. I am a flight scheduler for Delta. I'd be happy to update this list any time someone needs it (until they revamp our technology or I retire haha). Here is the list as of Feb. 2006. I went for the top 20, and I don't know the pet policies for Frontier (F9) or Airtran (FL) but I included them anyway. Southwest and America West are excluded. Again, these are the number of unique destinations served by what we call a "mainline jet" and excludes regional jets and "special product" jets like Delta's Song and United's Ted. Some of these destinations might be international.
