Aye cayman airways isnt exactly ryanair pricing for their short flights and still lose money hand over fist. I had a chuckle at AA's havana flights from miami terminal D (used to be hidden away on charters at the far end of E) now restrictions have been lifted somewhat (dont think you or i could get on it yet though so still not quite a modern happy world). Anyway, good luck, cubana looks interesting, but i couldnt bring myself to get on their planes for no rational reason. I'd look at that iberia fare, flew them recently and liked the seat a lot.
