To me the situation is quite simple. Definetely AA Citi Card.
I don't get it why people use the HHonors card and points reward system cause they suck. I look over their redemption, their hotels stays are incredible steep. THe arilines suck totally, more points/mile than direct in AAdvantage. I looked for redemptions in africa, southeast asia, indian ocean and south america and is not possible, they don't have awards for those cool places.therefore the HH reward system is useless
