  • Notes
  • Airline is the brand of Montgomery Ward. Please never use Airline as a search term for finding a radio or other equipment with the brand Airline. We used this term and the maker in the model name only here to make you receive this (only) if you type in Airline instead of the model number or the model name only. There were 3 models listed for Airline by the book "Radio Collectors Guide 1921-1932" lacking any details. These Airline we naturally have to keep under this "maker name" - even if it might be wrong in the book because otherwise one might think we are incomplete.
