Jacob knew Laban's reputation, so he was very explicit in his negotiation terms: "Rachel, your younger daughter." Good plan, but it didn't help. God had another plan in mind. See #genesis 29:18.

Was Leah meant to marry Esau? Some believe so because of the symmetry of events in the story: Jacob lied to Isaac in order to ensure he received Esau's blessing, so God arranged for Laban to lie to Jacob to ensure he received Esau's bride too. Leah and Rachel had to know what was going on, but they didn't tell Jacob. They were complicit in Laban's nuptial switcheroo.
