I'm trying to figure out when would be best to travel, as I'm planning to travel towards the end of November, again in December, and again in March, if possible. I want to use vacation all three of these times since I have some built in vacation days each of these months already, but don't know what dates I should block in order to get the best deals on airfare.
If it matters, I'll most likely be flying within the United States in November and December, and then hopefully somewhere in southeast Asia in March.
So the question: What are the cheapest days within a week or weeks within a month to fly?
