Lebanon airport will be pretty costly because it's VERY small (I live 1 mile away from Leb airport) & is mostly serviced by small regional airlines like Cape Air. They can only handle small jets, like 16 passenger sized. Manchester is serviced by large airlines like Delta & is a great alternative to Boston's Logan Airport, but it costs more than flying into Logan. Southwest airlines flies into both Manchester and Boston & depending on your departure airport, you can sometimes get decent deals on Southwest. Best of luck.
I believe there are commercial flights into Lebanon Airport. Manchester offers significantly more options
Manchester is a real airport, Lebanon is for private planes.
Lebanon NH has an airport
Manchester NH is my guess.
