There are 3 different airfield sizes, and they seem to generate different types of aircraft at different frequencies. At least with the NMMO airbases, the biggest airbases are in the home islands and Singapore and/or Hong Kong. There do tend to be a lot of merchants near these places; however, it's a lot easier to move a shipping lane than an airfield, and places like Truk tend be under-protected
