I think that even if Luffy usually trains alone, with Haki it will be a different matter and that he's going to learn how to use it in Amazon Lily, because when Luffy was with Marguerite -Kuja-, she mentioned that they are able to imbue Haki to her arrows to make them have more impact, and Luffy will actually want to become stronger after have failed in saving Ace, so in the coming chapters it's probable that someone will mention Haki and then Luffy will want to learn more in order to become stronger.
