Question for anyone with inside insight... When something like Boom announces: American said it too had paid a “non-refundable deposit” – it also did not say how much – as part of an agreement to buy up to 20 of the jets. Does that really mean AA paid them $1 (or a nominal amount) in return for the marketing impact of having AA's name mentioned in a few press releases?
