Check airline prices every Tuesday/Wednesday...that's typically when they post great deals.

Yesterday, United had LAX/SJU for $227 one way - that's why I was able to switch our mileage flight so easily. Now instead of LAX/IAD/SJU with a FOUR HOUR layover in Houston? We have LAX/ORD/SJU with under two hours in Chicago. I am a happy camper.
